Sounds like your installer was a turd-

Off, then Menu for User settings

Off, then Enter for Diagnostics

FAQ will help with this question

What are & how do I change the Settings in the DCT5100 for the TV Type, Y/Pb/Pr output, & 480 Override?

In reference to the DST problems. If the box can not receive updates or send back info it will not update the time. Check the "Non-Responding Box" part of the FAQ.

Does anyone know what steps he can take to correct this? Is there something he can do in the menu or does he need to call Comcast and have them send him some sort of signal?

I have the same problem with my 5100. I tried calling Comcast, they resent a signal, but that didn't work. After looking at the FAQ, I am pretty sure it has to do with my hook up (through my TV's converter). I will disconect tonight and try a direct line to see if I get an update overnight.

I came home today and found the box to be overly bright. I set the brightness of the TV down to the calibrated levels that work for the DVD player and the VCRs and found it to be satisfactory, perhaps still a bit brighter than normal. I checked the firmware level and sure enough, it was upgraded from 2.40 to 2.48. I don't recall if anyone else ran into this. So Seattle has finally caught up with the rest of the country. Software is still 50.00-1078.

I'll need to find some SD color bars again to check the calibration. I know the FAQ says the PQ upgrade is minor, but TV Japan does look less grainy than before.

Has anyone been having problems using their 5100 boxes. I'm in S. Jersey and mine seems to be on some kind of time delay. When I punch a channel number on the remote, the box doesn't "see" the numbers till 10, 20 or 30 seconds later. Then when it does change the channel, the program/signal doesn't come though right away and the info bar stays on the screen seemingly forever.

If anyone knows what might be causing this I would appreciate it. I'll be out most of Thursday and Friday so it won't bother me too much, but come the weekend, it would be nice if I could get it working correctly. BTW, I have tried a couple of remotes so I know it's not the batteries .

Over the past week or two I've noticed intermittent delays with my 5100 box. I would be happilly surfing channels, pause to watch a station, then try to change stations. The box would ignore me. This has happend a couple of times to me.

One thing I did notice, when this happens and I start pressing buttons on my remote, I see the LED on my remote light up, but I DON'T see the LED on the 5100 light up. This indicates to me there is some problem in the 5100 IR system. I have fresh batteries in my remote, and I have tried to use my Pronto remote too.

Like Kipper717 said, the 5100 seems stuck in this mode for about 30 seconds, then it all of a sudden springs to life. It appears to have at least received some of my commands because all of sudden the sequence of channels changes rapidly as if it was trying to catch up to my commands.

This seems to happen about once a day. I noticed the info bar problem too.

This seems to be a software glitch. This problem has been posted here before and just seems to come and go. Mine did it a couple of times after I received the "480 override" upgrade about 6 months ago. But it hasn't happened since.

New 5100 user...had my old sidecar setup replaced a couple of days ago...

I have 1 question, however (I searched, honestly)

I have a panny plasma (ED) and I'm having trouble with the 1080i output...I lose picture regularly (flashes in and out)...works fine with 720p and others....anybody else seen this? 1080i works fine, as that is what I previously used with my sidecar setup, as well as with my MyHD card....

Cheers,

Rich

That is strange. It could be a bad DCT5100, I've seen bad ones do some strange things. It also seems that the 5100 are more sensative to extremely low & high signal levels so this could also be causing problems, when it was installed did the tech check the signal level? How do your analog pictures look, particularly on the high channels (60 & up)? FWIW, I have the panny 42" EDTV and it works fine.

Unfortunately, the tech did not check the signal level when he was here....I have a variable attenuator that I can put inline to see if it's too strong of a signal and see if that clears it up.

As far as the 60+ channel quality, I really haven't had much time to really check them out...they quality overall of the non HD stuff is definately lower than my old 2000 series box, but I'm not sure if it's really worse, or if after reading re: this box that I'm perceiving it that way :P

Odd that the 720p stuff works fine, but 1080i not....

Oh, and one thing I forgot, I'm using an Inday component video switch (but was using it before as well)....one thing I need to check is what happens when I take the inday switch out of the loop...could be some sort of synch problem (when the 5100 changes from 480i to 1080i maybe the switch is getting confused)....

Anyway, thanks for the response...good to hear that you're working fine with the panny EDTV.

Cheers,

Rich

The time update problem on my 5100 is now fixed. Here is what I did: disconnected my cable wire set-up, then reconnected one direct line into the 5100 box input (instead of looping through the TV); turned off the cable box; called Comcast and had them send a signal to my box; turned on the box and TV; it worked (correct time).

Had the slow response problem several weeks ago. Gradually kept getting worse from once or twice a week to once or twice an hour. Finally, I unplugged the 5100, waited a few moments and then plugged it back in...immediately the problem went away and I've had no problem since. Of course, you have to wait awhile for the guide to rebuild. (When in doubt, reboot!)

Just got Mot DTC 5100 for Comcast HD in Chicago.

Need to get a transcoder to change the Component output to RGB. Don't care if it is the 5 cable (RGBHV) or the VGA (15 pin)... but would prefer better quality.

I've looked into a couple of transcoders Audio Authority (which doesn't note it supports HD bandwidth) and Key Digital (which I've read doesn't support the Mot 5100).

Anyway, anyone have a success story with a transcoder connected to the Mot 5100? Care to recommend a good one? Care to recommend a good place to buy?

Thanks in advance - you guys are priceless.

Don't know if this qualifies as a success story but I will report my situation.
As background I will state that my TV is a 4*3 that can only accept VGA at 1080i or 480p out of the transcoders. It will display 800*600 fine as well - so when I watch HD shows out of a computer card at either the 1080i or 800*600 I have perfect ability to either zoom HD or watch it letterboxed in a 16*9 format.

I tried the Audio Authority with the 5100 - it would only do 480p with my set and it had a green line on the right side as well. Fortunately DigitalConnections (https://www.dcpuraty.com/store/Product_List.asp?CID=3&CAT=VIDEO%20ACCESSORIES) allowed me to exchange with a Key Digital for the price difference. That gave me 1080i as well. However the signals are not as controllable as with a computer card (don't fit screen properly - at least with my 4*3 I get overscan in 480p and underscan in 1080i - the letterbox/pan and scan options do not work in 1080i with the Motorola 5100 so I end up watching HD shows out of the S-video to get proper letterboxing. And that causes problems because the guide is only available in the 1080i output unless your box is set to 480i when watching HD. Plus the Key digital has color bands transcoding the 1080i (but not the 480 p). I can't comment on the capability of the transcoder at 720 p because I can't display it. If your set can accept 720 p and is a 16*9 I would definitely go for the Key Digital over the Audio Authority (would recommend KD in any case - but you may have a totally acceptable situation if you can display at 720 p 16*9

Wacky. Thanks.

Don't you just wanna smack these manufacturers around?

RalphArch, Thanks. Anyone else? I have 16:9 plasma that I will drive with 1080i - if it matters for analysis.

Isn't this the same question Big Red is asking - with a breakout cable for the VGA out of the transcoder?

BTW as Big Red notes the Key digital is noted as incompatible with the 5100 here (http://www.copperbox.com/lite/popinfo.php?lc_code=KD-CTCA2) Perhaps that is the reason for my problems noted above. As I mentioned it works but its not 100% satisfactory. But maybe its the best option as I am only aware of one other transcoder and that performance is worse. We do need some success stories. Anyone using a KD @ 720p succesfully? Anyone getting perfect 1080i with a KD on a 16*9 set? (mine is 4*3 so I thought that could be the problem).

Since the KD does work with the Scientific Atlanta STB I wonder if COMCAST would support a different box in an area served mostly with 5100s?

The Extron CVC 200 should work, AVS is an Extron dealer.

Mot 5100 has component outputs. There is alot of confusion (as I've discovered) on component outputs and if they can be used directly with RGB - they can't. You need to buy a transcoder if you you want to go from component to RGB. Of course, just like with cables, you need one that supports the bandwidth you want to use... and of course, one that doesn't loose too much (if any) picture quality. That said, there are 3 or 4 on the market. I've read the most good things about the Key Digital, but there are others too... just do a search on "component RGB transcoder" on google or your favorite search engine. Note, you need to make sure you are going the right direction... they don't work both ways - and the prices are different.

The problem for me, even though I've noted alot of people seem to note the Key Digital is what they are using, I've only got heard of a couple of people that are noting it is working OK. And of course, there are a couple of people who noted specifically, it doesn't work reliably. So, I'm still doing research here... I'll post results when I find out for certain.

Anyway, there is some confusion at the Circut City, and even with some custom installers. They were under the impression you could just get a RGB breakout cable and connect the RGB (of the RGBHV) cables to the YPbPr component outputs and everything will work. Well it doesn't. After a bit of research (as they swore it would work if I did the connection right), I found out it probably comes from certain DVD players that have outputs that are labeled "Component" but actually swap from YPbPr to RGB seemingly automatically (or from a setup menu somewhere). It appears this is offered as a feature for the mass produced DVD players so different versions would not be required for different locations (for example Australia runs on RGB).

So, that is what I know... it is probably only 50% correct... but I do know you need a transcoder... unless you have a box that does the conversion for you (that is, a built in transcoder).

Hope this helps some,
BigRed

BTW - Thanks to those that have sent notes with their transcoder experiences.

Scientific Atlanta has a transcoder that was developed for use with their SA3100HD HD digital cable box. It does work with the 5100 from what I can tell. Your only option in getting one of them is to probably contact SA directly and see where that gets you. Worst case try contacting your local Cable Office and see if you can get any info from them (good luck). But if they use any Scientific Atlanta equipment in their system (analog cable boxes, amplifiers, line gear, ect.) they should be able to order them directly from SA. You can see it here:

http://www.sciatl.com/customers/subscriber%5Fpdfs/752184.pdf

On another note. In the Philly region we just got another firmware update.....Firmware is now 2.50. I'm not sure what exactly it did, I'm waiting for info to come back on exactly what it did. Could be DVI, analog PQ, or I/O activation. Which I have been told that wouldn't activate until 3rd qtr.

I'll keep you updated.

Hi does anybody know the code for controlling the 5100 with a new Samsung 61 inch dlp. Samsung lists codes for cable boxes but no Motorola?Thanks in advance.

If there is a code for GI or General Instruments, try that one.

I'm planning on connecting the 5100 to my 1st generation Mits set (VS-50803) using their RGB-CV10 adapter as the transcoder. Anyone else using this setup? Any issues?

Doubtful Comcast will rent them that soon, but maybe there will be an option to purchase them from retailers-- don't know how firmware differences may affect whether you can use a 6000 series versus the 5100 or 5200.

Here is the link to Motorola's website (also in the synopsis thread):

"Motorola Broadband Unveils Enhanced Digital Cable HDTV/PVR Set-Top Family – the DCT6000 Series" (http://www.motorola.com/mediacenter/news/detail/0,1958,2732_2217_23,00.html)

-Marginal tuner /w particularly poor perf on the lower analog channels.

Just got the 2.50 firmware in Ann Arbor (Detroit market). I could just be wishing, but it looks like analog via component might be better. I don't have a DVI cable, so can't verify that.

I've noticed that picture quality of chan 1-99 over component is sometimes better, sometimes worse. So, dunno if it's just having a "good day", or if the firmware really helped. Time will tell.

I have read through all the posts and am hoping you can help.

I've had the DCT5100 since JANUARY and Comcast of Central NJ is my cable provider and since I got the box it had the 2.40 firmware but i have not gotten any of the new firmware updates 2.48 and now 2.50. I know that Comcast rolls out the new firmwares slowly but should't I have gotten the 2.48 by now?

I went to watch TV through my 5100 today and every 10 seconds or so, the screen would go blank and I'd get a message to the effect of "sorry, this channel will be available shortly". It'd be up about 5 seconds, then I'd have picture and sound for another 10, and then the message again. All channels. I did not have any picture problems when bypassing my box.

I am in the Ann Arbor, MI area. I checked the firmware on Sunday and it was still at v2.48 - but I checked today after I noticed the problem, and it's v2.50... anyone else having issues with the update?

I called Comcast, and the rep told me that the box was not responding and most likely "dead". I asked if it might be a firmware problem, but she didn't know what firmware was. Luckily, they will have a new box here in a few hours... I wonder if it will be a few revs newer than my current one?

cclittle1:

For the last ten years that I've been with Media One (and then AT&T and later Comcast), the standard response for any problem that could not be fixed by them remotely resetting the box or requesting me to power cycle it, was to send out a tech to swap the box out. That had maybe a 5% success ratio on solving my cable problems, which were generally related to old wiring both inside my house (my problem) and outside (their problem).

After 10 years, I finally got a Comcast tech who correctly diagnosed the problems with the outside wiring. After two visits from him, which involved much cursing, ripping out of wiring, bolt-cutting of old Media One padlocks, etc., most all of my signal problems have been corrected, including frequent loss of HBO, terrible snow on Channels 2 & 3, and random "sorry, this channel will be available shortly" messages. I've got stable, crystal-clear reception of all channels including subscribed channels now, for going on three months. Ahhhh. I'm not sure, but I think my cable internet connection has been somewhat more reliable too.

I'd suggest you just keep complaining to Comcast, and having them send out idiot techs to swap out boxes, until you finally get the smart tech who can accurately diagnose and fix a problem more complicated than a bad box.

On the bright side, the Chicago area techs seem to be marginally better than the old Media One and AT&T techs.

I fixed mine the way you fix nearly any electronics problem: REBOOT! Try unplugging the power from your box, plug it back in, and see if it doesn't work (note the guide may take 20-30 minutes to repopulate itself).

I've got 2.50, which seems to be working fine.

Interesting followup - when the dispatcher called me to tell me that they would not be able to send a tech after all, due to a scheduling mixup, she was looking at my account and saw that they still had me down for a non-HD box. She updated my account so the box could be "provisioned" correctly and then had me turn it off and unplug it for 30 seconds. At least one of those things seemed to do the trick, and I'm now happily watching TV again.

Must be a few differences with this firmware for how cable companies talk to the boxes... ?

Analog PQ seems better, but still doesn't match that of my TV tuner itself.

And for the person who was asking about the speed of the chip in the 5100 before this quote should help:

The DCT6200 is the next generation of Motorola?s popular DCT5100 platform. Motorola has enhanced this set-top with an 800 MIPS internal processor ? an upgrade of over 150 percent.

That would put the 5100 at approximately 320 MIPS

Two days in a row I have come home to find my receiver outputting local NBC with the TV Off. (I leave receiver on all the time and use S/P-DIF out of the 5100). Thinking somehow the 5100 and TV power have gotton out of sync I turn on the TV (only) and behold still no picture. So I have to turn the 5100 on - no change in audio through all this (always on).

Is there any way to stop random audio startup of the 5100? I really don't want the audio on when no one is home.

RalphArch,

This is a first that I have heard of this. Please keep us updated on this if anything changes, this could potentially be a fairly big issue.

Willwhdtv,

You should have recieved these firmware updates by now. I would contact the local office and have them either setup for you to get a new box either by picking one up or sending a tech out. There is no reason you shouldn't have gotten these updates. Good Luck.

The Firmware 2.50, I found out did NOT enable DVI or do anything to the analogs. It made some minor fixes to the box in which you probably would have not noticed. The biggest one was the box used to skip channels on the flip bar when the channel up/down key was held, this update fixed that. See I told you it wasn't that big.

Word has it, that sometime around the beginning of 3rd quarter the DVI & Input A/V connections will be enabled.

And yes the fix for the intermittent picture problem caused by the 2.50 firmware, is to simply unplug the box and plug it back in.

I get the same thing Ralph and I'm not sure why. It hasn't always happened, just since the last upgrade I think. I also have the clock problem where if I turn the clock setting off, it stays frozen on whatever time I turned it off at and still displays. I think I'm going to have a tech come replace this box and see what happens with another one.

I believe I have noticed it like 3 or so times total - not very frequently at all in the six months or so I've had the 5100 (@48 on the code). Will keep an eye out for it but it is not that frequent.

Miatasm:

I have used your Moto 5100 FAQ at least a dozen times now, and have found it amazingly helpful. The regular Moto manual sucks, and Comcast CSR's seem untrained (at best), so I am not sure where I would be without the FAQ. I encourage anyone with a 5100 to use the FAQ. (Maybe I should be sending you my Comcast check?)

MIATASM

Thanks for your response on the firmware. I took your advice and called the office and they indicated that 2.40 is the latest firmware they are using. Why they are so behind I'm not sure but they also are behind on other things such as they did not priovide the NBA Allstar game on HD in February like some of the other Comcast areas in NJ.

I'll concur on this. About 5 years ago I was having issues with cable modem via Nashville's Intermedia (now Comcast). After not receiving good tech support from the people they sent for about 2 months, I called again and discovered that the person I was talking to in their call center used to work at the same company I used to work for. Once we recognized each other, she immediately dispatched "the A team". This was three of their best techs who weren't external contractors, whom most people got. They spent 4 hours running a new line between my condo and their splitter box, analyzing the signal at every point, and explained to me exactly what they were doing at every point.

The end result was a dramatic signal strength improvement that not only ended the cable modem problems, but also some cable TV issues, especially ghosts and snow on some of their analog lower-numbered channels. But you have to keep at these guys to send you the right people. It makes a whale of a difference.

I've been lurking for about 6 months, waiting to hop on the HDTV bandwagon.

Well, over the past couple of months, I've slowly been assembling my home theater, and today I finally got my Moto 5100 and HDTV. Even with the limited channels (Comcast - Boston Area), I'm still pretty pumped.

I went out and grabbed an optical cable so that I could get Dolby 5.1. Let me preface - I'll readily admit that my reciever isn't great. It's actually of the Home Theater in the Box variety (Rio 2030), but it was ideal for my price point and the size of my apartment.

Anyway - if I'm watching the analog channels, no problem - I get sound out of the optical, though there's some fairly consistent "clicking" - could be the cable I bought (I just wanted a cheapy to get things running, before I splurge for a good cable).

However, when I move to any of the HDTV channels, I get no sound. My reciever says it will work with inputs between 32-48kHz. I don't think that's the issue, but I suppose it could be.

Through the Comcast Guide, my SW Version is 50.00 - 1078, with a firmware of 08. Through the Diagnostic Menu, my Firmware is 2.48.

So - any idea why the optical isn't working on the HD channels?

Second question - any downside to turning off the 480 override? I've turned it off, which means my Tivo will no longer get the annoying Guide bar showing up on recordings, but what's the downside?

Thanks, and thanks to miatasm for the FAQ, which has been immensely helpful.

If you get the PBS HD channel, the Demo Loop offers nearly round the clock WOW, true HD. Occasionally, some of the other channels can provide WOW, but not as consistently.

RelDudeGOP, If you get the PBS Demo Loop (I think you do in West Orange) is probably the best overall for PQ & Color, but that doesn't start until 7pm same with Tonight Show w/Jay Leno (NBC) is also very good but thats not until 1130pm. The only HD you will see during the day is on HBO or SHOtime. Which in most cases aren't the best for showing the effects of HD. Best bet wait until 7pm and show him the PBS channel....

CrapMonkey?!?!?,

Its sounds like either your receiver or your cable is bad, does your receiver have a Coaxial Digital audio input that you could try?

Also if your DVD player has a optical output you could try that with the cable and the receiver to see if it has a similar problem. My guess would be the reciever, and 2nd choice would be the 5100.

The downfall to turning "off" the 480 override will be that whatever is chosen in the YPbPr section will be output all the time on the component output of the 5100. Which means you will have bars on the sides of all of your programming even the analog channels. If you want the best of both worlds put the 480 override on "480p" which will give you full screen on the analogs and will not output "guide and menu" on the Analog outputs of the 5100 (RF, S-video, composite). Good Luck.

k one other question
they're installing the box saturday. They're delivering the tv saturday. What happens if the cable company comes first? Will they still leave the box? I have a receipt to show them!! What will happen?

I agree that the PBS HD is generally the best quality HD stuff available on Comcast. Its quality can vary from show to show, but for the most part its very good.

Would you guys say that the quality of the PBS HD is on par with that shown on HDNet on DirecTv? I haven't been able to do side by side comparisions but without HDNet for the wow factor I find I can achieve that with PBS.

My only issue with PBS is that I frequently have signal breakups and digital pixelation. This happens as often as every few seconds during an entire show. Its definately in the signal and not in the source. Audio also drops out for a few seconds here and there. Anyone else experience this as well with PBS HD on Comcast?

RelDudeGOP: I believe Comcast will want to do the hook-up, so they might not leave the box if they get their first.

Lovingdvd: Comast does not offer HDNet, so I have no way to compare. Right now, some of the PBS-HD material is the gold standard for Comcast HD. I have never experience picture breakup/pixelation on PBS-HD, so my guess is that this is coming from your local PBS affiliate (they may be multicasting). Audio breakup seems to occur on just about every HD channel from time to time. Don't know why.

What is multicasting (so that I can ask them more about it)? Is it sending multiple station feeds on the same frequency or something like that?

Using their allotted channel bandwidth to broadcast more than one channel. They may also be broadcasting at low or reduced power. I am sure there are other possibilities.

okay i'm getting the box tomorrow and have some questions

1) is the digital audio out active for analog channels too? I know on my old box the dig coax wouldn't work for analog channels and i'd have to use analog audio outs for it. Does it make the sound better at all?

2) Which is the best way to output analog video? Component, svideo, composite, or rf? Is it better since i'd use the comb filter in my tv? It will be a pain to switch inputs though so i may just keep it on component.

I think you are right on the nose regarding multicasting as the possible issue. I remember hearing that they were only using a portion of the allocated space for the HD content and a portion for something else - sounds like multicasting to me. Without getting too far off topic, why does multicasting causing these frequent signal break ups?

crapmonkey(????),
I have the same problem, described in an earlier post. I switched out everything in the system and found that if I replace my old denon receiver I could get the digital audio on the premium and digital channels with a new sony receiver which I had borrowed. Neither comcast or denon have been of any help in explaining this. What receiver do you have?

I've run both a composite and component, but use the component output almost exclusively now. Analog broadcasts seem to look about the same either way, component might be slightly better.

RF would seem to be a complete waste of time, space, cable, and money.

S-video probably doesn't make sense, as the filter in your TV is likely better than the one in the Motorola box -- plus, my box doesn't have an S-video output, and I'm guessing yours won't either. Unless running s-video makes your switching easier (eg, if your VCR is using s-video), I wouldn't bother with it.

Audio: I believe the audio will work, but it won't be digital coming off the analog channels. Each receiver works differently, so may need to try alternative hookups.

Video: I agree with peebee on this. Experiment with all of your wiring options. I found that all Component works the best and requires least switching. S-Video was worse on mine. Analog channels through the 5100 box stretched onto a widescreen look pretty bad. Get used to that.

I really don't know the technical explanation. Perhaps someone else can chime in on this. It might be either reduced bitrates or that they are compressing the signal in order to transmit more information.

I have a cheesy little home theater in a box Rio 2030. It's worked well for everything, and as space is a premium in my apartment, I was looking for a all-in-one solution (if/when I move, I'll upgrade the system).

I'm beginning to wonder if it isn't the cheap optical cable that I used. I was noticing today that on the digital channels the sound "flickers" - my reciever will flicker on and off that the signal is Dolby Digital and I'll get sporadic sound.

Tomorrow I'm going to try a bunch of stuff - move the reciever and cable box out of my system and see if there's interference. Then I'm going to try running my other DVD player into the reciever - testing the optical input. If all that works, I'm going to head to Circuit City and grab a better optical cable. If it works, great. If not, they've got a good return policy.

If anyone has any other ideas, please let me know. The fact that I get some clicking on even the analog channels leads me to believe the cheap cable is definitely contributing to the problem.

--Ryan

Follow up to my last post:

This morning I hooked up my other DVD player to the reciever through the optical connection. Everything worked - the Dolby 5.1 lights lit up, sound came through and was full Dolby. Same with a DTS DVD.

So, it seems to me like the reciever is working just fine.

I moved the cable box and tried to get the optical cable to run straight into the reciever, attempting to minimize any interference. No go. Still get audio on the analog channels, but audio on the Digital channels is non-existent - or occasionally flickers in and out (mostly out). Nothing on the HD channels. It looks like the reciever tries to decode it - display flickers the Dolby light, but then it just drops and I get nothing.

So, I went out and replaced the cable. Nothing extravagant, just a better brand (Monster THX over Phillips) and shorter run. Same results.

Does anyone have any ideas? Could it be a bad cable box? Could it be the software version/firmware I'm running? Does the Moto 5100 somehow put out a different bitstream than a normal DVD player?

If someone has a spare reciever to loan me, I'd gladly test against that :)

--Ryan

Ryan,
Yea. Sounds just like my problem. My DVD player and sat receiver both output digital 5.1 sound thru the denon receiver without any problem. The 5100 outputs a digital signal that my denon 3200 receiver cannot read.
You could borrow a recever from a retailer with an easy return policy.
By the way the problem exists in both the optical and coaxial outputs. I had comcast replace the 5100 box-didn't help.
Brian

My processor has intermittent problems with the digital output of the DCT5100. The processor manufacturer says the cause is high jitter levels. They are working on a fix that will allow the processor to lock on to low quality digital sources such as the DCT5100. Maybe try a different processor or receiver.

So - does anyone know if this is something that could be fixed by Motorola with a firmware update?

I don't know the guts of the 5100, but depending on how that bitstream is handled, maybe they could add an option to filter it - sure you'd lose some of the highs and lows, but I'd rather have it work than not have it at all. Has anyone alerted Motorola to this issue (as it's obvious it affects a few people)?

Any other suggestions? I really don't have the room/funds to go grab a reciever, but maybe I could pick up some sort of inline filter?

I should go research the 5100 some more, put my Computer Engineering degree to use and see if I can't figure out something. Maybe I can find some inexpensive box to drop in between.

Sorry to be hijacking the thread - if y'all would rather I post this stuff elsewhere, let me know.

--Ryan

Ryan,

If it is a jitter problem, it could be solved by a jitter reduction device between the DCT5100 and your Receiver. I know of others who have succeeded in solving digital audio problems coming from satellite receivers using these devices.

Audio on with 5100 Off
Two days in a row I have come home to find my receiver outputting local NBC with the TV Off. (I leave receiver on all the time and use S/P-DIF out of the 5100). Thinking somehow the 5100 and TV power have gotton out of sync I turn on the TV (only) and behold still no picture. So I have to turn the 5100 on - no change in audio through all this (always on).
Is there any way to stop random audio startup of the 5100? I really don't want the audio on when no one is home.

I also have this problem. I leave my Yamaha receiver on all the time. When I am done watching TV, I power off the TV and power off the 5100; both sound and video are now off. I follow this rotine every day. Most of the time everything stays off. About once every two weeks I will come home and there is sound coming out of the speaker as if the 5100 has turned itself on. Audio is connected to Yamaha by Fiber optic connector.
I will have to check the next time to see if the 5100 is on or if only the audio is somehow turned on. I had thought that this may be happenig because the firmware was being updated. However I have been at 2.48 for a couple of months.

Anyone else with this problem? Any ideas on a solution?

I was original poster and it hasn't happened again (yet - 2.48 also). I do turn the power off /on with the red all on button. Even though the remote is programmed for the receiver the all on only works for the TV and the 5100. I have to select audio to get the remote to power on/off receiver. Probably is not a factor but just a difference in how you and I power on/off system - we both leave receiver on but in my case its because the all on is not comprehensive.

my cat would have to have extra special touch - as I was getting audio out of the 5100 box with it turned off. So I don't think its a random rf code.

Tim,
What is jitter? Where can I get a jitter reduction box?
Brian

Edit- found this "Jitter is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. As the name suggests, jitter can be thought of as shaky pulses. The deviation can be in terms of amplitude, phase timing, or the width of the signal pulse. Another definition is that it is "the period frequency displacement of the signal from its ideal location." Among the causes of jitter are electromagnetic interference (EMI) and crosstalk with other signals. Jitter can cause a display monitor to flicker; affect the ability of the processor in a personal computer to perform as intended; introduce clicks or other undesired effects in audio signals, and loss of transmitted data between network devices. The amount of allowable jitter depends greatly on the application. "

on hdtv channels like nbc and abc when they're not showing hdtv and the prog is upconverted are the sides slightly curved for everybody else? Or is it my tv? I noticed the bars on the sides are very slightly curved and just want to make sure its not my new television.
thanks

thanks It's your set.

okay i just bought it a week ago from best buy. I should exchange it for another?

bmel,

Think of jitter as timing errors in the bit-stream. The timing errors can result in audible effects. This is one of the main reasons that cheap cd players sound bright and harsh.

A popular jitter reducer is the Monarchy DIP. I think Camelot makes one as well. These devices are usually used to improve the sound of cd players by reducing jitter levels, but I used one to allow my processor to lock to a satellite receiver in a previous system.

I'm having the same issues with the digital audio dropouts. I've had the box for around a month and it worked great untill last week. I get audio for stations 0-100 over either coax or optical (tried two different optical cables). I used to get DD5.1 (when avail.) etc on the other channels and now only silence. I can still get audio for every channel over the RCAs.

The poor tech support rep. at Comcast didn't even know what the digital audio outputs on the box were for! However they tried and they're going to replace the box this weekend. I'll let you know if that helps.

You would prolly be better off learning how to converge your CRT's as well as fix the pincusion on your set. You should be able to find the info easy enough by asking in your TV's brand forum or doing an internet search.

Ordered a Monarchy DIP jitter reduction box. I'll post my results in a few days.
Brian

Anne Arundel County, Maryland.--Noticed I had received another firmware upgrade overnight. I am now up to firmware version 2.50 but I still do not see any change in the poor analog channel quality. Looks like the biggest change this made was in the menu and that was not all that much. No DVI activation in this one.

DD5.1 is back! I realized that my audio problems seemed to start around the time I figured out how to enable the 480p output for regular 4:3 TV material. I set the box back to 480i for the non-HD stuff and the audio over the digital output came back for all the channels.

Maybe that's why they're tripling the processor power for the DCT-6000! It must bog down the processor so bad that it affects the processing and output of the audio for the digitally encoded cable channels.

The cable guy will be here tomorrow to drop the new box off. I’ll play with it and post what I find out, including the firmware revision…etc.

Well it happened again this morning (audio out of the receiver with the Moto 5100 Off) - but a slightly different circumstance when I heard the Receiver blaring out an emergency flood warning on the local channel 8 which I never tune to.

In this case the box remained turned off and there was no residual audio out of the box after the warning.

Seems like a feature I would want to retain in any event; so I wouldn't want the occasional audio out with the box off to be fixed in some kind of fashion that would eliminate something that seems like a well-designed warning system I was unaware of.

update may 28
today came home with the weather channel on receiver (5100 off). When I turned the TV on there was a vertical bar of video on right side out of the (normal) components. The video was of the weather channel when I viewed TV channel 3 (RF bypass). When I turned the 5100 on reverted to last channel and all was back to normal.

Moncarchy DIP jitter reduction box is not the answer. If I want digital audio from the digital channels with the 5100 I'm gonna need a new receiver.
Brian

Does anyone know of a contact at Motorola we could possibly send this info on problems with digital audio to?

I've seen posts here and on a few other message boards of people having this same problem. I'm guessing that there's at least some stuff that Moto could try through software/firmware updates to improve the problem. I'm not saying that they necessarily can solve it, just that it's worth a shot, especially if they aren't aware of the issue.

--Ryan

Personally, I'm just sick of the vertical line that runs down the right side of the picture.

Is it worth exchanging for another box? This looks more like a bug than an actual hardware problem.

OK Just got a couple of 5100 boxes installed by comcast. I have the same problem with the digital audio on my Denon receiver but not on my HK Receiver. I got nothing but an overload signal on the Denon until I hit the attenuator button. Then I got the in and our that others are having. To me it looks like the signal from the 5100 is too hot for the Denon. If anyone from Motorola is reading this board please lower the power if possible by firmware ....

I don't know if it's too hot or something else. I tried a radioshack attenuator in the line without success.

What model Denon receiver are you using that you are having this problem with?

It is their early DD model(3200 I think). My Harmon Kardon has no problem playing the DD signal from the other 5100 but the Dennon went staright to overload. When I put the attenuator button on I started to a signal but it would come and go.

I have the Denon 3200 also. Same problem with the audio. No digital audio from digital channels. On my unit the attenuator button only seems to function when the denon is in the analog mode . It does not seem to have any effect at all in digital mode. Perhaps you are not in digital input mode?
Brian

bmel and Trevorsplace,

Curious if this happens when using coaxial and/or optical connections? I use a Denon 3803 and do not have this problem.

It is the optical input that I am having the problem with.
I have not tried the coax input as that is used by my music server and takes priority in this setup.

I have the same result coaxial or optical.
Someone is reporting a similar problem with an H/K receiver and a Zenith STB here (http://www.avsforum.com/avs-vb/showthread.php?s=&threadid=261158)
The Denon 3200 is a relatively old receiver. It doesn't even do DTS. I'll likely just end up replacing it. As a last resort I sent a note to denon tech support. They never acutually answer questions, but I thought I might get lucky .
Brian

Anyone using the Denon 3803? It would be nice to get some confirmation that the audio does not have the problems being reported by the Denon 3200 users before I purchase at 3803. Thanks.

I've been using the 5100 optical out to my 3802 for serveral months without any problems.

Story in today's Inquirer about Comcast's plans here. (http://www.philly.com/mld/philly/business/5907047.htm)

The story says: "Comcast is testing, or will test, digital recorders from at least three manufacturers, including Motorola, over the coming year. Motorola's version should become available to Comcast customers later this year, but prices have not been set, according to the company."

Just had the 5100 installed 2 days ago (Gallatin, TN) and on most of my digital channels i get the message "ONE MOMENT PLEASE This channel should be available shortly" The installer said that the message would go away in about 45 min. Some of the digital channels work fine (i.e. I can get CBS and ABC in HD but I get the message above on NBC...upsetting because I work for the local NBC affiliate!!!!!!!)
Comcast was no help and can't even schedule a new box to be delivered until next week!
I have unplugged the box, left the box off, and left the box on...the problem still remains. Anyone else had this issue?

My software version is 50.00-1078
Firmware version is 00

P.S. Also the installer was complaining about the local office not having the box "ready"...he was a little upset because he had to wait for the soft/firmware download when he hooked up the box.

videocam,

Check your rf splitters, many splitters do not have the bandwidth to allow the 2 way communications between the box and the head office. Your splitters should have bandwidth 5 MHz to 1 GHz, if they do not replace them or remove them. This should solve your problem.

lovingdvd,

I have been using the 3803 for 6 to 7 months now, and I do not have a problem with audio, and the rcvr is very good.

I live in West Orange, NJ and seem to have received the 2.50 firmware last night. Does anyone know what this changed or fixed?
Thanks
Jonathan

RelDudeGOP, the FAQ has what you are looking for.

videocam, One moment please is usually caused when the the box loses contact with that digital carrier. That why you will notice multiple digital channels are missing (up to 8 channels). If its an HD channel it may only be one or two channels missing (only 2 hd channels can fit in one carrier with cable) Essentially the problem is not enough signal on that particular frequency. Check you wiring/splitters/ect. for poor/loose/corroded connectors and replace accordingly. But this should have all been done at the time of install. There are exceptions to this like bad box, glitch in the addressability/accounting system, ect. But most likely its an RF issue. Good Luck.

on most of my digital channels i get the message "ONE MOMENT PLEASE This channel should be available shortly"

I had this same problem after the last firmware upgrade - it turned out that their system still thought I had an analog box. Once they reprovisioned it for HD, it worked fine again. All channels were showing the error - even the <100 ones. The first phone rep wanted to replace the box, but the second one knew better.

Good luck!

ever since i got 2.50 i can't access any VOD? It says one moment please then gives me the error message after like 2 minutes!!
anyone else experiencing this?

Happen to notice that some people had gotten some new firmware. So I checked my box and, sure enough, it looks like I got the upgrad (Comcast Boston).

Even better for me - it looks like part of the software change might have been some changes to the digital audio output. On the same reciever where I got nearly no digital audio previously, I'm now getting some audio. It's intermittent, and still not listenable, but some digital stations seem to work nearly ok!

If someone from Motorola is out there reading the thread - whatever change you've made recently helped. Maybe tweak it a bit more.

Anyone else seeing the same phenomenon with moderately improved digital audio with the new firmware?

Of course, with RCN just about to offer HD in my area, I'm thinking about taking them up on their offer - especially if Comcast keeps dragging their feet in regards to adding new channels.

Anyone know what box RCN uses?

I have the Moto 5100 receiver in Calgary. Right now I'm watching the NBA on ABC. To my suprise, there are noticeably less motion artifacts when I have the box set to 1080i instead of 720p. Has anyone else experienced this? Maybe Shaw Cable is converting the 720p feed to 1080i? Any thoughts?

Oh, I have a 480p panel, so it's not just 1080i being my display's native rate.

I am splitting my signal even further (up to 6 ways now) and will be buying an amp for the cable. It is a Channel Master that has a bandwidth 5 to 900 Mhz so that should be OK but I don't think it is two way. I called Comcast technical help and they said it didn't need to be two-way. Is that true for the 5100?

I do not presently have the 5100- HD service is supposed to start here in the Bay Area on 6/3.

I'm pretty sure the 5100 does require 2-way communication.

Also check to make sure you don't have any signal modulated onto seemingly "unused" cable channels. They're ALL used. That was my problem. I had my security cameras modulated onto analog cable ch. 87-89-91, which SEEMED to be un-used by Comcast. But even though they don't provide those analog channels in my area, those frequencies are still used for their digital channels. In my case, it resulted in a permanent "ONE MOMENT PLEASE - this channel will be available shortly..." message, for a dozen or more digital channels. To fix this, I made sure the cable runs going into my 5100s were split off before the modulator.

If your system doesn't require 2-way, it will eventually. If the amplifier you are getting is capable of 5-900mhz it should pass 2-way, the only problem is that cable amplifier amplifies only the forward frequencies, it actually only passes the return frequencies, in most cases it actually attenuates the return 1 or 2 db. I would inquire at the cable company and tell the you want to buy an amp from them. Out here (S Jersey) it costs about $45 installed. Good Luck.

Sorry if this isn't the right thread or if this has been answered before.

The 1080i signal is inherently in 16:9 format. It is sent to your TV similar to the way an anamorphic DVD is. You should change the TV's viewing mode to be the same as you use for anamorphic DVDs. This will activate the vertical compression.

My 5100 defaults back to channel 5 every time the box is turned off and then back on. I checked the "d" codes looking for the option when using the "ok/select" button after power-up as suggested in previous messages button didn't see this specifically.

Is there any way to change this option to "remember previous channel" instead of always reverting back to channel 5 (I realize one way is to not turn off the box, :) ) but the box is frequently turned off by others.

Thanks,
Adam

adamf,

This "feature" is usually encoded in the software of the box, which is controlled by your cable company, this is usually not something that is controlled by the user.

thanks for the quick answer, but when i play a dvd on my toshiba 5700
i never change any settings and it shows it in OAR. I put
part of star wars II on last night just to be sure and it was correct.
If this is any help to the puzzle, when I was getting HD OTA on my
samsung box, i would have to go into the samsung menu and change
the ratio settings, depending on the channel i was watching.
My tv is the toshiba TN50x81.
When i watch the HD channels through analog input the ratios are
correct....if that is any help.
thanks again.

Rouge1.

I live on the Mainline (just outside Philadelphia). I have had the 5100 since January 03 and I have received the 2.50 s/w update.

Andy

I am in Montgomery Co, PA and still have 2.48.

I clicked select after pressing power and checked some of the settings because my hdtv has been kinda pixelated lately. Some of my settings are the following:
OOB:
SNR 19.6DB - Fair
AGC 19% - Good
In Band:
SNR 34.0DB - Good
AGC 79% - Poor (one I'm most worried about)

Would an amp help this or is this how it's supposed to be. What are all of your numbers? Thanks guys!

These numbers aren't good at all, in most cases I take these numbers with a grain of salt, unless (big unless) you are having a problem. When you turned the box off and pressed select were you tuned to the channel you werehaving the most problems with? If so, there is a definate problem. Most of these problems, however are in house problems not cable "system" problems. Start checking you cables, connectors & splitters for any signs of corrosion, water, decay, poor connectivity (loose), ect. And no an amp would not help. Good Luck.

Seems like there addressing the audio problem from the optical output. I can get a little audio with my Rotel but it isn't very clear. No audio with Dolby Digital audio though.

We need another firmware upgrade!!!!

I've read of these things... now after many months, I have them?!?

My Motorola 5100 box has been rebooting. No data download. It seems to reboot several times, then settle down, sometimes it's OK for days (this has been going on for about 3 weeks). Also, it has, for the first time, symptoms I've read about here but never experienced - s l o w (really slow) response to channel change, menu drawn in practically line by line, picture is pretty quick to rebuild but sometimes I can wait for what seems like 20 seconds for the sound to reappear. Is this likely a defective box or something Comcast (Montgomery County, MD) is up to recently? I rarely get picture "glitches" though it does happen, but the glitches don't seem to correspond with the rebooting. I have a cable modem as well and it's behaving perfectly. Comcast is coming out Monday afternoon for a swap; if there is any advice out there as to what might be happening, or what to tell the tech other than the obvious, I'd appreciate any responses! Thanks.

Bill,
I've been having the same problems. The menu would leave like a line on the screen and the channel changing would take forever. Sometimes I'd change the channel and like it would freeze for 5 minutes and I was so afraid of burn in that I turned my tv off. This only started happening after the 2.50 firmware download it seems.

Guys,

Try to unplug the box from the power for about a minute or so - and then plug it back in. It'll take a bit of time (about a half-hour) for the info to download again - but your channels should change as quickly as they used to.

Give it a shot - and let me know.

David

yeh thats how i usually fix it and it only happens once every couple days so its not such a big deal. Just kinda of a pain that's all.

Maybe slightly OT, but:

Comcast in the SF Bay Area is about to rollout HD Cable using the Moto 5100. This is a godsend for most of us who cannot get OTA HD in this hilly area.

Speaking generally, how does the cable HD PQ compare with OTA, and how does it compare with DirecTV for HBO and Showtime?

You shouldn't see any difference in PQ compared to OTA or Dish. Virtually Identical.

Not necessarily true. Cable HD uses a compressed signal that may not look as good as OTA. This is supposedly one of the reasons for CBS's dispute with Comcast.

Nope. Cable modulates the signal differently it doesn't compress it. I have done extensive testing, and compared directly side by side there is no visual difference in PQ when compared to OTA's. This may vary in other cable systems but my systems (I have access to 2) there is no difference.

I have a slightly off topic question. I have basic cable service with comcast, if I buy the 5100 and hook it up to my HDTV set will I get the HDTV signal?

Thanks

You can't buy a 5100. It is a offered through the cable company for a monthly fee. Even if you could buy one, it would have to be formatted by a set-up signal from the cable company.

But semi good news if you live in San Jose, the largest city in the Bay Area, where most folks here won't see cable HDTV until at least 2005. The good thing about that is , hopefully, when in 2005 when cable HDTV comes to San Jose, the latest and greatest equipment(with most of the bugs worked out) will be available.

I am finally getting comcast HD service this saturday. i know they use the 5100 box which from some sketches I have seen has a DVI output that should work with my SONY 57WV600. anyone using the 5100 DVI out to their TV? also, shocked to see circuit city selling the DVI cable for $100, does the 5100 come with a cable?

thanks!

Congrats - you will really like the 5100 and the Comcast Digital service. HOWEVER, just a heads up that your 5100 may not have a DVI port on it. Some of them do, and some don't. I had to jump through hoops for a few days and go through three boxes before they finally found me one with DVI. If you don't get one by default, and are persistent you may be able to get one.

This is all well and good but here comes the BUT - the DVI port is not yet enabled. There are rumors in this thread that DVI may be supported in a firmware upgrade in the summer or fall, but I'm not very hopeful. Just glad I have the DVI port so its one less hoop I need to jump through when it does become available. Let us know how it works out.

For the past two nights in a row, my 5100 shutdown at roughly 8:00 PM EST. It was like someone unplugged the box, waiting about 5 seconds, and then plugged it back in. I did not lose power or have any quick surge/fluctuation that would have caused this. It certainly seems like it was a reset signal or some sort sent by Comcast to the box.

The unit shutdown completely, then after about 10 seconds came back on. The guide data and time following the shutdown were lost and slowly reloaded/downloaded over the next 15 - 30 minutes.

I've had this set up now for over two months and have never seen this behavior before. Now its happened two times in a row, at about the same time.

I'm in Montgomery County MD. Anyone else experiencing this? Anyone know what could be causing it? And if its being initiated by Comcast, what is the purpose?

Thanks.

Greetings

I have been using the Comcast 5100 in the Boston area for a couple of months. I have experienced some of the problems discussed before.

For example this morning at 4am the sound started comming out of my speakers. This was discussed before. I leave the audio receiver on all the time and shut off the Toshibe 50HDX81 and shut off the Comcast 5100 (but still left plugged in). This morning the sound came on (from the 5100 to the audio receiver through optical audio cable). The 5100 was still off and when I turned on the TV there was no picture until I turned on the Motorola 5100. Thus somehow with the 5100 off, the audio portion of the 5100 turns itself on and sends sounds to the speakers (do not have a cat).

A second issue is that in Boston area for the past two days have not been able to get channel 807 which is HD channel 7 (NBC). When switching to this channel there is no sound and video freezes at previous channel. I hope this is a local issue that has nothing to do with the 5100.

A third issue is one that numerous respondents to this board have temporarily fixed by unplugging the 5100 for a minute and a half. This has to do with slow channel switching and freezing. This morning I unplugged the 5100 for 2 minutes and plugged it back in. Still do not get channel 807 (HD version of NBC), so the unplugging does not fix everything but does fix slow channel switching.

I have also had some issues with intermittent pixels lost and dropping of audio in some movies on HBO and Showtime. This has happend the last couple of days and I don't know if this is because of too much compression in the signal from Comcast or if it is caused by too many users causing a weaker signal that droops some pixels and audio? A couple of times I missed some dialogue which may have been important to the movie.

When the 5100 is working correctly (most of the time), the picture is incredible. I never seem to get the pixel or audio drops from the PBS channel (802) endless loop which gives incredible picture and sound, just like being there. The picture quality from the 5100 is almost identical to the picture quality I was getting from my Samsung 151 over the air receiver.

I am at 2.50 version so the 2.5 did not fix the ocasional turning on of the audio when the 5100 itself is actually off but still plugged in.

I really like the HD picture quality from the 5100 and the 5.1 sound is also very good but not quite as incredible as the 5.1 sound from DVD movies (probably less compression?). The HD picture quality is however far superior to DVD movie picture quality.

Bonus

Does 2.50 fix the problem with the analog 1-99 Picture quality problem on the 5100?

I'm in Montgomery County too. I believe the same thing happend on my 5100. I got home just before 8 and I noticed none of the stations had any of their guide information. I waited for about 1/2 hour and still no information. I eventually got up, pulled the power cord off, waited 10 seconds then plugged it back in. After about 10 minutes all of the info was reloaded.

To the person asking about the 2.50 firmware fixing the analog channels....I noticed no difference between 2.48 and 2.50.

The only point I would add - that you may not have seen/remembered from my previous posting - is that one time this happened to me during a severe weather (I believe tornado) warning. So I no longer think of this audio situation as a problem but as a feature I do not want defeated (perhaps worked on to start up less frequently or only during emergencies) In my case it might happen every 2 weeks or so.

All "new" 5100 STB's Manufactured by Motorola have the DVI-D port on board. It is not enabled, yet, expect early 3rd qtr. Comcast as of now will NOT be suppling a DVI cable. You can get DVI cables for under $20 with a little searching on the web.

The 2.50 firmware update info is in the FAQ.

Bonus,

If you have not had NBC in a while check the OTA HDTV forums to see if NBC is maybe offline in your area. Its happened several times in Philly.
AFA pixelation commonly called "microblocking" this may be an issue with the cabling in your home. The 5100 is pretty finicky when it comes to noise and signal problems caused by poor wiring, fittings, splitters, ect. Check the FAQ later tonight I will be posting some info on how to read the Diagnostic screens in the 5100. This may help you.

Yeah, ever since I got the 2.50 firmware update last week, my box keeps rebooting and locking up on channel changes. The lockups are really scary because I don't want my TV to burn in (I'm pretty paranoid about that).

Why don't they test these firmwares before they push them out?

I guess because they figured all customers are their Alpha/Beta testers?

Tonight my 5100 turned off, rebooted, and turned back on two times between about 8:00 - 10:00 PM. This is the third night in a row its done it in this time frame. Tonight it came right in the middle of the hockey game - quite annoying.

FWIW there may not be anything special about this time - its probably just that these are the hours I typically have it powered on so that's when it happens and I notice it.

Can anyone explain what is going on and whether there is a fix coming that may resolve it?

I live outside of Philadelphia. I read about this problem in the Thread a few weeks ago. This past week we were awoken in the middle of the night by people speaking in our living room -- Turns out we experienced the same problem. As an FYI, our 5100 has the 2.50 S/W.

Andy

Malvern area, philly suburbs - got a 5100 2 days ago to replace the 2000+sidecar. First box wouldn't authorize and he had to get another (happened to a couple other installers that morning; apparently a bad batch). Second box took it's download (the new batch hadn't been set up yet) and was all happy. Much faster, and much better integrated than the old sidecar setup!

One interesting tidbit about the philly area at least and maybe elsewhere - he said that CBS digital was coming soon.

We've seen pauses when using the guide - my wife (also a engineer in the cable industry) loves the faster guide, but sometimes the guide freezes and displays "please wait a moment". She tends to flip through pages and times pretty fast. We should be getting a Harmony SST-768 remote (sweet!) in the mail any day now (we bought at the SCTE cable show - $150 shipped instead of the normal $300+shipping), and that has a built-in guide which might reduce the need for the ugly/evil/no-longer-as-slow TVGuide guide.

Man, do I wish they'd ditch the stupid ads and show 1 or 2 hours of shows like the sat boxes do! Not to mention favorite lists. Ah well, that's what we get for the 5000-series boxes running in 2000-compatible mode. I'm really hoping Comcast trials the 620x boxes in my headend this fall. Really really nice, and include SD-PVR and HD-PVR functionality.

I came yesterday to find that my box was stuck at 12:00, and there was no guide available. I checked the firmware and sure enough it had changed to 2.50. I unplugged the box for about 30 seconds and then fired it up...but after waiting about 20 minutes still no guide and the time still reads 12:00. I'm not sure what this is supposed to fix...but I didn't have any complaints about the box until now.....any suggestions?

It seems like the 2.50 firmware is unstable and causing various, significant issues for lots of people. The good news I guess is that since so many people are affected I would think these issues will get prompt attention and hopefully be resolved shortly with another firmware update.

I too came home last night to find this issue. The guide was dead and 12:00 was on the clock. Hope they come up with a fix fast!

Just got comcast to install the Moto 5100 on my Mitsu WS-65807 TV. He connected it with component cables to the "Component 480i/480p" input on the back of the TV and not the DTV component video ports that include 1080i. I'm able to view all of my channels including my HDTV channels but they don't seem to be in HD since the TV says '480i'. Any ideas? Also, unplugging the component cables doesn't cut the video feed, it seems the TV is getting its signal from the standard cable TV cable that is bypassed through the 5100 to the VCR and back to the TV (sorry for being so confusing). Any ideas? Thanks.

Dave

Plug the Component cables to the DTV input of your Mitsu. Press your input button on your remote until you get to the DTV input. You should be able to see some sort of picture.

If you don't see a DTV input, then you need to turn it on. Hit "menu" then "input assignment" (I think) (maybe "setup" first) then arrow to "DTV" and right arrow to highlight the right column. Then arrow until it says YPbPr.

Do this also if the DTV input displays a primarily green picture when you select it.

Don't forget to read the FAQ below. This will tell you how to setup the resolutions and format (1080i, 720p, ect.)

Hope this helps. Good Luck.

I have been having the audio drop-outs on the HDTV HBO and Showtime channels like others on this thread. Here are the possible problem results from the diags:

1) Firmware Version: 00 not "04 or later"
2) Preview Software Version: 50.00-1078 not "51.00-1096 or later"
3) Remod Chanel is 3 not 4 ("terminal never initialized" - what does this mean?)
4) In-band AGC: Poor, 82% -> 99% not "Good or Fair"
5) Upstream Modem Center Freq: 10.4 Mhz (not "8.096Mhz or 11.168Mhz")

BTW, there is only one high-quality splitter between the cable box and the outside line (although I think the cable company has one just before it enters the house)

How can I fix these audio dropout problems? They make watching the HDTV channels very unpleasant.

rung,

Your AGC is way too high. Call and have a service tech come out, you have a problem.

I'm in Montgomery County as well. I had posted earlier that Crumbcast disavowed all knowledge of any problems and said a visit would be required to swap the box (still can't let the customer swap a 5100). So... it was replaced last Monday and has rebooted 4x that I know of since. Guess it wasn't the box, eh? Does Crum... I mean Comcast EVER thoroughly diagnose a problem? Do the outside techs EVER actually speak to the "genius at the head end?" Of course customers can't. This week I'm also noticing deficiences in the old bitstream on the digital channels, yielding "glitches" in picture and/or sound now and then. It's also brilliant that the "Emergency" tests wipe out the sound for... hours sometimes (switch to another channel, all is OK). Is anyone home at Comcast?

Friend of mine in PG County just got a 5100 connected. Nothing but glitches, unwatchable.

Service: not provided, please try your call again later ;(

I'm glad that Comcast responds quickly now, and that they rolled out the hi-def boxes fairly quickly, but it's no fun to be right in the middle of a movie and "click" - and then it could happen 10 minutes later! They have to be sending out a reboot signal or the 5100's are REALLY messed up with this s/w version!

Thanks. I'll give them a call. What causes this - a weak signal?

The audio sync on my 5100 is terrible with the analog channels. We don't have HDTV locals yet (I'm in Seattle) so this ruins about 50% of our recorded programming.

Are there any fixes for this? If I call Comcast I expect they'll just want to swap out the box and I'll have the same problem again...

It is too bad that I can't have the Tivo tune in analog channels directly and only use the 5100 for DTV and HDTV signals.

Many DTV channels (for me specifically IFC) look terrible -- I assume that is just Comcast overcompressing and nothing that I can fix on the 5100?

The problem could be the way you have the Tivo hooked up. Have you tried trying the watching the signal directly (w/o the Tivo)?

Alex,

I don't have a Tivo, so maybe I'm talking through my @ss, but my ReplayTV can handle antenna-in for analog and cable-box in for DTV and HDTV. I would think that Tivo can do it also, for the price of a splitter.

FWIW, my analog is acceptable with the 5100, and I no longer split the signal.

Claude

Alex,

You can hook the TiVo directly to your cable without going through the cable box. The trick is that you have to SETUP the TiVo from the very beginning, uplug your TiVo wait a few minutes and then start from the very beginning of the SETUP. This is how I use my TiVo unit.

donjulio:

I can use the Tivo without a cable box (and did this for many years). As far as I know you can't use the Tivo with a cable box and use the Tivo tuner for the analog channels, but the cable box tuner for the encrypted or digital channels.

We get tons of additional programming on the 5100 that aren't HDTV and thus are still interesting to record onto the Tivo.

Unplugging your Tivo won't step you through setup either, at least not my Tivo. It stores the configuration on the hard disk.

alex

Anyone using the Moto 5100 and ReplayTv? If so please explain you cable hook-up between them and the HDTV. More importantly the Video Hook-ups...

Thanks, Ryan

I have two Motorola boxes from Comcast, one is the 5100 and the other is the standard digital cable box (for use in the other room). Don't know the model # of that one offhand. The audio sync problem is present on both of them. I think the standard box has it worse, actually.

So I don't know whether this is necessarily a 5100 problem, a Motorola problem, or a Comcast problem.

I think it is a Motorola or 5100 problem, as we had no audio sync problems when we only had analog cable. They also go away if I remove the 5100 and tune with the Tivo directly (but that is an annoying many hour process to go back and forth).

It would be nice if you could tune the a/v sync through the setup menus on the 5100. I also only have problems with analog cable channels, HDTV and digital channels are fine.

alex

I have read with great interest the discussion on volume levels and the DCT5100. My question concerns accessing the audio menu on the DCT5100. Moreover, the only menu page that I have been able to locate is the basic stat up menu taht addresses issues like 480i override and closed caption offerings. Any help would be greatly appreciated.

Best regards,

I have a three-way splitter and watch all ways: Cable Box/HDTV direct without Tivo, analog (no cable box) w/o Tivo, Cable Box/HDTV w/ Tivo and analog (no cable box) w/ Tivo. The last way requires a Tivo hack. I haven't had any audio-sync problems but I do get audio drop-outs on the HDTV channels. Have you run through the 5100 diags yet?

Goto Main Menu --> setup --> audio

This only allows for changes to the compression settings on the Audio for analog channels only when using analog audio ouput only.

This question is addressed in the FAQ below:

Great FAQ Page Miatasm. Thank You!

I'm getting the 5100 thursday from Comcast. I'll be sure to make use of your page.

Analog Video transfer can be done by RF, Composite, & S-Video. HD video transfer can be done by Component (Y/Pb/Pr) (analog) & DVI-D (digital) (DVI enabled boxes started being produced in Jan of 2003). The DVI output is HDCP compliant, which is a copyright protection that disables the ability to record HD programming. At this time it is not active. (3/03)

CSR at comcast told me today that I would be able to use DVI... can you confirm that ?

DVI is not yet enabled, but all boxes are being manufactured with them, activation is slated for possibly 3rd qrt.

I heard a rumor that supposedly the DVI port will not be enabled on the 5100 but rather they'd introduce DVI one the next generation PVR box that is rolled out eventually. Probably is unfounded but curious if anyone else has heard this.

In the Philadelphia area- I had my 5100 installed by Comcast 2 weeks ago. The Comcast installer stated that the DVI is active, and I asked him twice just to confirm.
Haven't tried it yet though.....not sure how to test with purchasing a DVI cable??

I'm in Philadelphia. DVI is not active with the current firmware.

thanks Chris.
No surprise that the Comcast installer didn't know what he was talking about.

I wouldn't hold my breath. This is what Comcast told me back in March.

I know that my question below does not really belong in this thread but I posted it in the Audio hardware section and no one replied so I thought maybe someone here can answer it.

I have a 10-year old audio system (Atlantic pattern surround home system) that has 3 live inputs. Everything has worked fine and I have always made sure that all the inputs except the one that I was using was turned off.

Comcast replaced my cable box with the HDTV cable box today. I'm up and running but still need to do some adjusting with regard to the PVR. Up to now the output of the cable box went to my Replay TV PVR. With the HDTV box I will have the S-video output go to the Replay (and from there to the S-video input on my Sony 11HT projector) and the component output to the 11HT. It would be convenient if I could have the audio go to the Replay AND directly to my sound system so that I do not have to turn on the Replay if I do not need it.

My question is: What would happen if I turn on the Replay and my audio system is getting the same input on two lines? I suppose that I could try it and hopefully nothing gets damaged, but I thought maybe that someone here could tell me in advance.

Thanks.

mka,

Assuming that you have the RTV and 5100 audio going to different inputs on your audio system (i.e., you haven't rigged up some Y-connector "backwards"), you will have no problems.

AFAIK, I've never heard of any reason to have other sources turned off UNLESS you did one of the Y-connector kludges, but those are strongly discouraged. I have to assume that your audio system, no matter how old, has an input selector (those were standard much more than 10 years ago).

Enjoy your system (... I have a 10HT and Replay, and enjoy both). You do not want to go through the Replay if you're watching live HD, though for time shifting, it does a not-bad job with downrezzed HD.

Claude

Thanks for your response, Claude.

Actually, my surround system does NOT have a select input function which is precisely why I asked. Also, one thing that I did not think about originally is the fact that the 5100 has only one analog audio output so that I would have to split the signal: one would have to go directly to the sound system and the other would go to the Replay and then back to the sound system.

At the moment I have the sound go to the Replay and then from there to my sound system. I have the component output of the 5100 go to the Sony 11HT and S-Video to the Replay. Fortunately, everything seems to be working fine with this arrangement and I am really happy to finally have HDTV (I had been waiting for this for over 10 years). The only disadvantage is that to watch TV I have to turn on the Replay (even if I don't need it - because the Replay does not pass the sound through without being on), switch the 11HT to S-Video, tune into a channel (the Replay does not always come on tuned in), click on the bypass function for the Replay, and then switch to the B component input on the 11HT. This is rather awkward.

Maybe I should let sleeping dogs lie and enjoy what I have.

mka,

Well, you know what they say about making assumptions :)

I don't know your audio setup, but perhaps it's time to invest in a moderate receiver, whether AV or stereo. Or, if you're not in the market for that, you might want to consider getting an inexpensive A/B switch.

Splitting an analog audio signal is no problem (i.e., one source, Y-connector, two targets). The reverse is not recommended, though apparently (I'm no EE) it can work fine depending on the input and output impedences of the equipment involved.

You should definitely enjoy what you have, but there's no harm in waking up a sleeping dog to see if he wants to go outside and play.

I just had Comcast install their HD service yesterday and the fellow that came out was very knowledgeable about the hardware and all the configurations to interface into AV equipment (I was impressed). I brought up the DVI issue and he indicated that in order to save cost on the box they elected not to have the DVI activated because Motorola increases the cost to the cable operators for every option that is activated.

Do to the fact I had a DVI cable from my monitor available he tried it anyway and of course it was OFF.:(

I seem to be having low audio problems for my HD channels.

All my HD channels have low audio from the RCA l/r analog
audio ports. When I tune between analog ABC and ABC-HD,
the difference in audio level is quite noticeable. Non-HD digital
cable channel audio levels are fine too. I've already maxed the
tuner box volume levels.

The same problem is present for coax spdif, but to a lesser degree,
and I don't notice it as much because I can turn my stereo louder than
what I can do with the builtin tv speakers. I need to use the RCA
l/r because I record the downconverted svideo using ReplayTV. I find
with anything that is recorded off of HD I have to crank the TV volume
way up and then when I'm done, I crank it back down.

I've read the FAQ regarding DD signal levels and light/heavy/none
compression. I've played with what I think is every combination
of compression, stereo/matrix mode, etc. but it seems to have little to
no effect on my analog RCA l/r audio output.

My box is running
software: 50.00-1078
firmware: 02.48

I'm in the sf bay area and they recently started rolling out HDTV service.
Any pointers on things I can try?

Low volume on the HD channels is normal. The help menus on the setup screens will explain this.

I think those are a different version of help files from what I have because
my help files for setup->audio don't say anything about low HD audio
levels being normal.

I think one could say it is expected behavior, but I just can't see how
it can be considered normal. I need to crank my tv audio to 60-70% to
hear the audio vs 15-20% for analog channels. It is quite disconcerting
when channel surfing from HD to analog and the audio starts blaring.

This typically applies to not just HD channels, but all digital channels. See the 5100 FAQ. If you set the audio for "heavy" compression, the levels will be closer. "Light" and "none" cause a major level difference between DD sources and analog sources - at least through the analog RCA audio outputs.

Here is the current link for that FAQ:

http://www.cjhengineering.com/5100faq.htm

And here is the relevant section:

Why do the HD channels & Digital channels seem quiet, compared to the Analog channels (Ch. 99 and below) when using Digital Audio Output (Optical/Coax)?

This has mostly to do with the dynamic range of the Dolby Digital Signals. Read through the next question & its listed links to get a better idea on what this means.

What do the Audio Compression / Matrix Stereo settings mean, in the Audio portion of the Main Menu of the 5100?

This refers to the Dolby Reference levels for Audio output on the ANALOG Channels only when using ANY ANALOG audio output. These settings DO NOT effect the sound when using the Digital Audio outputs (Optical or Coax) & DO NOT effect the sound on the Digital Channels regardless of audio outputs used (Analog or Digital). There was a very good post on the AVSforum.com DCT5100 Topic that explained what each setting meant in the Audio Set-up menu of the DCT5100. I copied it and posted it separately from the forum to this page (http://mywebpages.comcast.net/miatasm/HT/dolby.htm). Thanks to -- hwc -- on AVSforum.com for doing the research. It can also be seen on Page 24 of the Official DCT5100 Topic on AVSforum.com

Ok thanks guys, HEAVY audio compression works ok for me.

I had read that FAQ and the Dolby Digital extra page already but for some
reason my head kept thinking compression was reducing the dynamic
range and thus reducing the volumes. It didn't occur till I reread it
that HEAVY compression *boosts* quiet sounds as well as *limiting*
loud sounds.

Given the behavior I now observe, I found this portion of the FAQ especially confusing:What do the Audio Compression / Matrix Stereo settings mean, in the Audio portion of the Main Menu of the 5100?

This refers to the Dolby Reference levels for Audio output on the ANALOG Channels only when using ANY ANALOG audio output. These settings DO NOT effect the sound when using the Digital Audio outputs (Optical or Coax) & DO NOT effect the sound on the Digital Channels regardless of audio outputs used (Analog or Digital). In fact the compression settings *do* "affect the sound on the Digital Channels
regardless of audio outputs used (Analog or Digital)". The settings affect the analog
audio outputs, not the digital outputs. As implemented, they seem specifically
designed to affect the Digital Channels (output on analog RCA L/R and RF)

What I've found is (with v2.48 firmware)

1) Using *analog output* (RCA L/R)
a) The compression settings have little to no effect on analog tv channels
b) For digital tv channels (audio transmitted as digital stream) HEAVY compression is needed
to convert the audio levels to something that is comparable to normal analog tv channel audio levels
c) HEAVY compression, in addition to *limiting* loud sounds, *boosts* quiet sounds

2) Using *digital output* (spdif coax/optical)
a) The compression settings have little to no effect on any tv channel, regardless of whether
it is analog or digital
b) The analog l/r audio for analog tv channels is being converted to digital PCM by the DCT-5100
c) The audio levels (analog converted to digital) referenced in 1b) are much louder than
pure (transmitted) digital audio levels for the equivalent HD channel.

I've concluded the compression settings of NONE, LIGHT, HEAVY, as implemented, are
designed to map *digital* audio levels to something that is usable when compared to the
audio levels of standard analog tv channels

This is the exact opposite of the impression I got from reading the FAQ intro. The inconsistency
in the FAQ blurb clouded my mind to what the Dolby Digital page was actually saying.

"This refers to the Dolby Reference levels for Audio output on the ANALOG Channels only when using ANY ANALOG audio output."
should be
"This refers to the Dolby Reference levels for Audio output on the DIGITAL Channels only when using ANY ANALOG audio output."

"These settings [...] DO NOT effect the sound on the Digital Channels regardless of audio outputs used (Analog or Digital)."
should be
"These settings [...] DO NOT effect the sound on the Analog Channels regardless of audio outputs used (Analog or Digital)."

After 4 months with the 5100 fed with componnt cables into my ED Plasma, I remain increasingly dissatisfied with SD chanels (everything other then the 5 HD chanels comcast provides which are generally superb) and have two questions.
1. Will a DVI enabled box (when activated by Comcast later this year) materially help the SD channels if I use DVI into my panel, or is it still garbage-in-garbage out.
2. Can an outboard processor materially improve the quality of SD channels?

One of problems with cable is the heavy compression on most SD channels. I bet HBO looks much better than most. I think they have a rule about limiting the amount of compression. I don't think an outboard processor will help that much - GIGO - garbage in, garbage out.

I have a few hopefully simple questions about the DCT5100... I've tried searching and FAQs, and don't have the patience to read 72 pages worth of posts in this thread (although I've skimmed a bunch)...

1 - Are people generally happy with it? I've read about horrible PQ on the analog channels, audio sync problems, audio level problems, etc.

2 - Does anyone know when Comcast is planning to upgrade to the DCT6XXX series offerings? The deal with Comcast was announced by Motorola last month. I'm especially interested in the DCT6208 with HD PVR capability. Given Comcast will charge extra for the PVR version, they should gladly let you upgrade to the 6208. Do they offer a PVR STB in any markets yet? Anyone know what they charge?

3 - How does one add DVI to the DCT5100?

We've been very happy with the 5100. Only downside for us is the audio compression thing.

Comcast said publicly they expected to start offering settop-PVR in the fall in the philadelphia region (probably means Q1 of '04 in reality). The assumption is this means the DCT-62xx boxes, but it could be 5200's in theory.

DVI is on the 5100. It is only enabled if the cable operator decides to. At this point, Comcast is not enabling DVI, and they haven't said why (whether it's software issues, hardware issues, or encryption/HDCP/etc issues, etc).

Thanks for the reply. By "audio compresssion" do you mean the difference in level between DD and regular audio tracks? Or do you mean the audio sync problem that several here are complaining about?

I could live with the level difference problem. I could NOT live with everything looking like a poorly dubbed film with lips and audio out of sync. Apparently this is only happening on the analog channels?

I also don't understand why it's not possible to use another device to view the analog channels if the DCT5100 does a poor job? You just split the signal before the DCT5100 (which you're going to want to do anyway if you have any other TVs in the house, etc.) and go from there? There are some earlier posts that imply this isn't possible?

One last question: Will the DCT5100 output HD programming simultaneously in both HD (via the component) and 480i (via composite or S-Video)? I ask, because I'm curious if you can record HD programming from the composite or S-Video outputs onto a PVR, etc? I read it has macrovision, but that aside, does it downconvert the HD content?

Yes it will output composite, svideo, and component simultaneously.

If component is 480p or >, for the HD channels, cable box UI will only
be displayed on component out, not composite/svideo (no big loss)

ReplayTV PVR records from svideo fine for the HD channels. It actually
looks quite nice at medium record quality.

Make sure you set audio compression to HEAVY or your sound levels
on the HD channels output through RCA L/R to PVR will be very low.

the lack of a guide on the composite output (unless the output is set to 480i) is a big loss

yes I know I can switch TV output to components to see the guide - but as my family says I am the only one that knows how to operate the TV.

For simplicity of use the guide should be included on the composite out - regardless of the setting you have for the component out.

(BTW for me the need for composite output arises from the way my 4*3 TV and COMCAST box combine to only display HD and SD shows in correct aspect ratios when set to 480i or on the composites. It comes close at 480p but is still off center slightly and somewhat miss-sized. 1080i is definitely miss-sized; basically an HD show fills the screen with some material not displayed on the edges.) Letterboxing and pan/scan only work in 480p or 480i display modes; but this does include the composite output when 1080i is selected allowing viewing of HD material either letterboxed or zoomed on the composite out- with all the picture on screen and sized correctly)

If you're only interested in the analog channels, you can use a 1GHz splitter and run a feed directly to the TV, unless you're near the limit of signal strength (for example, if you already have a bunch of cable drops). The simultaneous output is mostly useful for attaching a VCR. A splitter is most useful if you have something recording the output of the 5100 and want to watch something else.

If you want to see both sets of channels, why not use the HD set via component?

We watch only via component outputs for now. That may change slightly since we have two replayTVs on order - but they have their own guide, so feeding them from the svideo output is probably ok. The only downside is that the replay channel-surfing speed is much slower, and I suspect my wife will prefer to surf via the 5100 remote when the replay isn't recording something - but she HATES the TVGuide guide anyways, so if she wants to use the guide she'll use the replay guide. If the replay wants to record, it will force a channel change - the only danger is if my wife or inlaws don't notice the red light and decide to surf (the replay would record their surfing session).

As for what I find problematic about the sound, it's that to keep consistent levels I need to use heavy compression. Compression _bad_ (especially if you have a good audio system).

The channel surfing in v5.0 OS for 5k series is improved. About 3.5-4
seconds (1-1.5 seconds quicker than before). Also you can fine tune the
IR parameters down to 50ms instead of default 200ms for more
improvement.

If you let ReplayTV think it is on a particular channel and instead use
the Motorola remote to change channels on the cable box (so your RTV
doesn't have to go through IR blaster and rebuffering), channel change
times are down to 1.5-2 seconds total. It is quite usable for me.

Also there is a short cut, which many people have started using. If you
hit the up arrow, it will bring up the HUD which will show you the show
titles of what is playing. If you continue to press up/down it will cycle
through the different channels so you can easily pick what you want
to watch without "surfing" All the while when you are doing this, your
current channel continues normal broadcast.

The compression only affects the analog L/R. From what I can tell, it
isn't really compression in the same sense as mpg. They compress
the dynamic range by bumping up the sound levels on low audio and
shrinking the sound levels on loud sounds.

If you have a nice stereo, you probably hook up via optical or coax SPDIF
and audio compression doesn't affect these outputs. This is good and
bad. Good because there is no modification of the sound. Bad in that
the analog channels are louder than the HD channels.

Maybe I'm wrong - but the only setup adjustment I have ever found (on the 5100) adjusts the on screen material (guide, etc.) and has no impact on the actual picture.

My transcoder (Key Digital component to VGA) does have a slight horizontal centering adjustment - but I recently discovered that dip switches need to be set contrary to the Key Digital recommendations for optimal viewing in 480p (like I said I am optimizing and its pretty good but not perfect), which disables the horizontal adjustment

My TV also has controls for picture size and location - but there is one setting for all modes. It is currently perfect for TV tuner reception - including the rf out of the 5100, Computer Monitor viewing (VGA-1 including MyHD HD tuner card output) component input (but this is only 480i capable- and it is perfect out of the 5100 on the components without a transcoder if I leave it in 480i), and SVideo. So it doesn't make sense to adjust the TV to get one mode right out of the COMCAST box.

Yes, "compression" of audio in the radio/TV world is dynamic range compression - making quiet things louder usually. "Good" radio stations (nowadays, probably only public stations and some college stations) avoid compression like the plague. (I was a radio DJ in college at WRPI, a 10Kwatt station in upstate NY.)

Yeah, the "flip" guide (very similar to the one in the 5100) is a good thing.

Of course, I'm still waiting for my Replay's to ship. :-(

Is anyone able to reveive VOD services with this box.

I got it to work today, but the odd thing is that I don't get all of the options that I see on another non-HD cable box in my house.

For instance, I cannot get Showtime and TMC on Demand using this box, but can on my other non-HD box.

Is there any reason why I can't get the same VOD services on this HD box just like the non-HD digital box?

Does anyone know how to reset the 5100? I need to also reset the EEPROMS IC. I just upgrated from the old motorola digital box, does anyone know if the hi-pass filter trick works on this model?

It should work exactly like the other boxes in your house. But I do know when we first launched the VOD services in my area, the two boxes (HD non-HD) weren't in sync. It seems the be a platform issue but you are in NJ and we have had this resolved for awhile now, at least in South Jersey.

the rep on the phone thinks it may be a problem with the box and have setup a tech dispatch on Monday June 30th.

what firmware do you guys down there have? as of now, i am currently running 02.40 firmware, with S/W version 51.00 - 1132 Firmware 00.

this is so frustrating because i don't want to have to go in the front room to watch TV, when i can do this in the comfort of my own bedroom.

what was the resolution to the problem you guys were having?

Anyone have HD channels without DIgital Subscription? I never watch the digital channels, but want my HD channels..
is this possible?

It is possible to get the HD locals (and HD HBO/SHO) without digital cable. You may need to talk to them a while, though, or ask for a supervisor. I think there's been discussion of it here in this thread, and/or in the HDTV local info forum (search for Comcast). You will need to pay a rental for the HD box.

Originally posted by rouge1

Rouge1,

Where are you located? The other response is correct, you can get HD without digital. The installation should run you $29.95 or less, depending on the area where you live. The monthly box rental fee for just HD is $6.35 (in Montco).

Digital Classic is $9.95/month and Digital+ is $14.95 a month (the box is included). The difference between Classic and + is the number of channels available. Both offer the Music Choice channels, Access to PPV and VOD, and On-Screen Program Guide. Also, with Digital+, you can usually get into a promotion for 3 months at half-price.

Lastly, if your a sports fan, CSN-HD is only available with Digital.

Hope this helps.

I'm currently using code set 0276 with DCT-5100 but 0476 also works.
4476 has triple digit problem.

Speaking of codes - Does anyone have a 5100 component ccf file for the 5100? I'm getting around to reprogrammng my Pronto TSU2000 and remotecentral only has earlier series of Motorola cable remotes.

The 5100 codes seem to be compatible w/ the DCT-2000. I've been using the codes from one of the DCT-2000 .ccf files on remotecentral.com with no problems.

Actually, I read something disturbing relating to this - I was planning on doing this after I move, but here's what I read - you can only get hdtv for no additional cost if you subscribe to BASIC cable only...I guess the law says that someone who's getting basic (i.e. networks only, no cnn, no espn, etc.) cannot be forced to pay for digital cable to get hdtv.

So, if I want cnn, for example, then I have to pay for digital cable to get hdtv!

Can anyone confirm this detail?

Ron,

At least through Comcast, you can add HDTV locals to whatever service you have for $5...Be that any of their analog services ...Basic, Expanded Basic (which included CNN) or on top of a digital service.

I don't believe there's anything that says they have to supply HDTV for free to basic subscribers (as part of the must carry rules, they can supply any signal they want)

Ron, I agree with davisdog - you can get HD locals if you have non-digital, non-basic service, at least through Comcast.

CSN=HS is on;y available the digital plus and is not available with digital basic. In HD will be available with digital basic only.

Yes, mine definately runs quite hot as well.

I am unable to get audio output from the RCA stereo out simultaneous with my Coax digital. I am trying to route the sound to a second stereo receiver. The FAQ states that audio is output through all simultaneously.

What am I missing here? Is there a set-up or menu option where I must instruct the 5100 to use those outputs in addition to the digital outs?

The specs for the 5100 indicate to leave a 2" space for the top and sides.
The unit does run warm.

Your are not missing anything it should work. Make sure you are not plugged into the audio "output" jacks. They are right above the inputs, this is the only thing I can think of.

Weird Random Lockups in DCT-5100

I've been getting random lockups in the guide recently. When performing normal guide functions such as scrolling through the schedule, entering a channel number to skip to, or bringing up the info, the guide becomes non-responsive to the remote or the front panel buttons. After a minute or so, the guide exits back to the program and then starts working again. It's acting a lot like what we call an abend or a GPF in the computing community.

I tried unplugging the unit for two minutes. I later had an incident of severe slowdown during channel changes, which cleared up after a minute or two.

Box is a DCT-5100, software level is 50.1078, firmware level is 2.48. I am on the Seattle Comcast system. Is anyone else experiencing these symptoms, or is it time to swap out the box.

Al, I'm in Seattle with 2-week-old DCT5100 and have not experienced any of those problems. I find the DCT Guide UI very counter-intuitive in some spots, but that's not what you are describing.

Stew

Attention Motorola - please consider adding an option to the 5100 that would enable us to easily switch between 720p and 1080i using the user menus and remote.

I know this can be done by using the service menu, but that requires getting up, turning off the 5100, entering the service menu, etc.

If HD content is in 720p, then it looks best if I have the STB set at 720p so its passed natively to my display.

If its in 1080i, it looks best to pass it to my display device and let my display scale it to 720p.

Therefore for the best PQ I simply cannot just leave the 5100 set at 720p or 1080i - I need to switch it to 720p when watching ABC, and 1080i otherwise.

Now FOX has announced they will soon start with HD, and it will be in the 720p format as well. This means even more of a need to easily switch back and forth between 720p and 1080i output modes.

I am thankful that the 5100 let's me change the resolution at all. But certianly it would be much nicer if I could easily change it back and forth using the remote.

If anyone at Motorola is reading this - please consider it. Thanks.

Per my last message - does anyone know if its possible to enter the service menu of the 5100 (where the controls are for selecting 720p vs. 1080i) by using the remote? I've been under the impression that you have to enter the service mode by using the buttons on the 5100, but maybe you can use the remote?

Yes, you use the same buttons on the remote that you use on the front panel. -- "Power" off & "Menu".

This problem has been experienced by many of us at one time or another and it just seems to go away on its own, it seems to be a bug in the software. It was a fairly rare occurance for me. Maybe once every 2 weeks.

My box doesn't do it anymore, Firmware 2.50. But it stopped freezing before I got 2.50.

I am just getting clicking either through coaxial or optical outputs. Won't the box downrez to PCM? I am running it through my audio dac that wont' accept any kind of bitrate DD stream etc. I have no problem outputting my DVD player this way, so is 5100 related.

I recently inquired about receiving HD w/out the digital package and the CSR told me I could do that, but that all the digital box features would be locked out except for the ABC,NBC and PBS HD channels, no CSN HD. That is, no pay per view, no VOD etc. As it is now I have digital plus w/ Starz, Encore, and HBO for about $75/month. (Which is $10 less than the listed price for this package, so I'm going to leave well enough alone for now.)

Got some questions for you 5100 experts. Got into the beta program for Adelphia's SoCal HD rollout. Am using a Mitsubishi RGB-CV10 transcoder (purchased just recently in anticipation) to connect the 5100 to my 1st gen Mits (vs-50803) set. 1st time I'd had an HD source to check out my sets HD inputs. When viewing HD source from the 5100 on the HD input, the color is way off. Have to turn up hue control all the way to red and still isn't ok. On downconverted analog input color is ok. Am looking for a way to tell where source of problem is - 5100, transcoder or set. Any suggestions? I'd like to get some tech support from Mits on this since 2 of 3 components are theirs, but their web site doesn't seem to have tech support. Tried their "customer service" number where I sat for 30 minutes without ever talking to anyone. Has anyone else had any similar color issues - i.e. differences between the analog and digital inputs using the 5100 (or with one of the 1st gen Mits sets)?

I recently inquired about receiving HD w/out the digital package and the CSR told me I could do that, but that all the digital box features would be locked out except for the ABC,NBC and PBS HD channels, no CSN HD. That is, no pay per view, no VOD etc.

This is what happened to me when got an HDTV and the cable guy came to take away the regular cable box and hook up the 5100. I had to call them up to have them turn on my digital service. Then I got into a dispute with Comcast about the amount of credit I was entitled to as the result of the interrupted digital service, but that's another story.

My VOD Service issues have been resolved. I was impressed with the Cable guy who came out today. He managed to fix my low signal problems, as well as VOD.

Good going Comcast.:)

Are any of you guys converters from satellite? If so how would you compare the non-hd/analog PQ of cable to the non-hd/"digital" PQ of Satellite? Would really appreciate some opinions.

Hey folks, does your 5100 generate a fair amount of heat? Mine is the hottest box in my cabinet -- hotter than TiVo, which has a hard drive always spinning.

Hot? You could fry an egg on it. :D

I think I had issues with mine and the heat too. It seemed to reset once an hour or so when I had my DirecTV HD STB turned on. The DirecTV box was on top of it an generated a fair amount of heat itself. Once I did some rearranging and moved the DirecTV box off the Motorolla, the resetting disappeared. I guess they were serious about the 2-inch space on top and bottom huh?

Three words - Not Even Close. I have both, but only to watch my locals in HD through cable. Every other channel I watch through DirecTV because the picture quality is far superior. Once my locals are available OTA, I'll be dumping cable. That is unless they roll out a nice big fat HD package before I get to that point.

Not Even Close.

I agree with sangs. I use the 5100 for HD channels only and watch everything else through my DirecTivo.

I noticed that the 5100 puts out a signal when its powered off. Why is this? All other components I've worked with actually turn the circuits off when powered off.

My front projector has a feature where if it does not receive a signal within 15 minutes it shutdown. The other day I turned off the 5100 but my attempt to shutdown the projector did not work without me knowing. I returned 24 hours later to find that the projector was still running. If the 5100 did not put out a signal when powered off, then the pj would have shutdown. This would be the desirable behavior.

What kind of signal are you running to your projector? s-video, video, compnt? it might have something to do with passthru.

I notice the same thing with the audio SPDIF optical output. i.e., it does not shut off when the DCT5100 is in standby mode. If it did, then my receiver could automatically switch to the analog audio outputs from my TV whenever I turned off the cable box, but since the DCT5100 continues to deliver an output signal when it is "off", I must switch the receiver's audio input manually. I can't understand why the DCT5100 functions this way.

Off course I also can't understand why it is not programmed with discrete ON and OFF remote control codes either. Apparently the designers haven't done much study on how these devices should optimally function together with other components in a home theater system.

As noted elsewhere in this thread, the Moto 5100 box has very poor picture quality on the non-HD channels. Hopefully this may be resolved sometime in the future with a firmware update.

So the next question is, how do the HD channels on cable compare to HD from satellite?

I have to disagree with those that say the non HD output of the 5100 is much worse than DirecTV. The local channels I agree are not as good but most other channels I watch are as good or better than DirecTV. DirecTV have been compressing the channels so much that several of the channels I like to watch had become crap. These same channels on cable are great. I think a lot of people blame the 5100 but it could be your cable signal as mine PQ is just fine. After being with DirecTv since conception I don't regret switching.

Just got my 5100 setup on Monday...Cox in SoCal. My HTB (Philips LX3500) only has a Optical Output....no input. Will I be able to process 5.1 signals through the RCA Composite jacks? (5100 to Philips Receiver)

I plan on replacing this HTB sometime...but it was free (rebate with tv) and the Progressive Scan DVD in it is great......

The signal is component. When I run the same component cables from my projector to my DVD player, the projector says "No signal" when I power off the DVD player (and therefore the pj will shutdown in 15 minutes unless it sees a signal = what I want). If I hook the same cables up to the 5100 my pj shows nothing except black, but continues to show that it is receiving a signal even though the 5100 is off. If I unplug the 5100, then the pj shows its getting no signal.

When viewing HD source from the 5100 on the HD input, the color is way off. Have to turn up hue control all the way to red and still isn't ok. On downconverted analog input color is ok.

It's probably all of the above. Unless you have your HDTV properly calibrated it will not display an accurate picture, but if you feed it identical sources, it would logically display the same picture regardless of quality, but you are not feeding it identical sources.

Mostly I would look to the 5100 as the source of a problem because that's just the way it works. Some TVs have multiple inputs and let you configure the hue, etc. separately for each input. If your TV has this, it's the best way to connect your equipment.

In my case I have this, but I have two HD sources and all of my inputs are in use (DVD player via component as well). I use a Zenith DTV-1080 via component cables and a HiPix card in a PC via VGA (50' cable from basement!) -> transcoder -> component. Both are switched through my receiver but share the same input on my HDTV as the others are all in use. There is no adjustment on the Zenith box but there is on the HiPix. So I have manually toggled back and forth between inputs and adjusted the hue, saturation, etc. of the HiPix output to match the Zenith. Perhaps you can hook up your cables something like this.

I don't know everything about the Mitsu Transcoder, but from my expierence, when you send the Y,Pb,Pr signal to an input designed for RGB/HV then your picture will be mostly green, which I'm assuming is what you are getting. This is common with Mitsubishi TV's because the HD input on their television's are switchable from RBG to YPbPr. But when you throw the transcoder into the mix it shouldn't matter, it should convert the Y,Pb,Pr to RBG/HV, from the looks of it, it's not doing this. I would check in the menus of the TV, or on the box itself, to see if there is a switch to change it from RGB to YPbPr. I would also try connecting the 5100 directly to the TV, just matching the colors up, to see if you get the same result. If you do then connect your DVD player to the trancoder to see if it works, so on and so forth. Hope this helps and let us know what you find out.

As of last week, I had my first HDTV delivered. Yesterday, Comcast came and swapped out my STB for the DCT5100. When I purchased my tv, the owner of the store was telling me about the 5100 and that sometime late this year, the firewire would become active on it. He said to try to get a box with the firewire port, but unfortunately the one the installer brought me did not have it. I've been reading this thread for a while now and my eyes are getting blurry, so I figured that I'd just ask. I'm kind of anxious to see how my Mistubishi tv will interface with it. Anyone able to tell me the story on the firewire? Thanks.

Hello,

Repeating what I have seen online, DVI may be enabled later this year on Moto 5100s so equipped. Firewire so far is not an option. It may surface on the 6200s. It is not clear whether the Firewire connection will support more than just displays.

Ditto That!

I had previously reported that the 5100 continues to send a 1080i signal down the component output even when powered off. As an update - actually it is a black 480i signal it sends out when powered off.

Anyone know if there is any way to force it to send no signal at all when powered off? Thanks.

Well after 75 pages of forum posts, my 5100 FAQ has hit 10,000 hits, I have replied to most of the 200+ e-mails & PM's I have received, which has allowed me to keep the FAQ updated with info. Nothing new is on the horizon as far as I know, but it shouldn't be too much longer before DVI is active, and the 6200's will start being beta tested, somewhere(I hope!).

I'm now working on another project that will be a supplement to the 5100 FAQ. And hoping for some feedback from here.

This will be a Troubleshooting guide to common problems / quirks encountered with HDTV's & Home theater equipment in general (receivers, ect.) when interacting with, specifically the 5100, but it will have some function outside of the 5100 also. (I won't be limiting the content to the 5100 only, but since its what I see the most of....)

Here is an example:

Some Phillips, Akai, Samsung HDTV's do not accept 480i on the Comoponent HD input, only 480p & 1080i. So this will cause a scrambled picture when tuned to a non HD channel, when the 480 override is set to 480i (which is factory defaults).

Another:

When connected to a Mitsubishi HDTV the picture is clear but mostly Green. This is because the HD input is set to accept an RGB/HV signal & not a YPbPr (component) signal. Can be switched in the setup menu of the TV.

You get the point.

So feel free to e-mail me with suggestions or even questions about your particular equipment, please include Make & Model, and a brief description of your quirk / problem. The Guide will be broken down by Manufacture & Models affected.

Most of the info I have gotten so far is from the forum here, but I do find that sometimes a question is posted about a particular problem and is never followed up by the original poster as to how it was fixed. And even if it was posted on the forum doesn't necessarily mean I saw it or took note of it. So even if it has been beaten to death on the forum you can send it to me just in case.

As far as the 5100 always outputting a signal, I ken that it did it but it never affected my setup, so I didn't think much of it. From the sounds of it this should be taken care of. Same thing with Discrete On/Off codes. We'll see.

Any way to disable the red idiot light on the box telling me I have a spam message waiting?

Delete the message.......

The problem is that I am tired of deleting the spam almost every day now. I would like to disable the message function, or at least the annoying red light short of putting black tape in the front of the 5100.

I have Comcast, and you can turn off the messages function...

Try going into "menu," "setup," "guide" and then select the "off" option for "messages."

i now have firmware 2.52. Anyone know what that changed?

I think that added the On-Demand VOD service. Just press the menu button and see what you get now.

I talked to a rep a few days ago and she said they just added it the night before.
