I am definitely eagerly awaiting DS. So far none of the channels here have been converted, but I'm hoping before the end of the year.

Well, I got my PIII which is now sitting on top of my older 6412, and I have to deal with blocking off the IR one at a time from each. One suggestion was to do this with cardboard.

I'm having trouble doing that, even when I cover the entire display window.

I'm not sure, but it looks like the sensor is at the very left hand side of the display window.

Any success stories about placement would be appreciated.

I have a Phase 3 box from Comcast and have a problem with HDMI. I ordered that 6' cable from svideo[dot]com mentioned earlier in this thread and noticed that the HDMI picture was fuzzier and a lot duller. I have a Samsung 32" LCD with picture-in-picture, so I was able to do a side-by-side comparison of the component video quality and the HDMI video quality. The HDMI looked like crap compared to the component signal.

I thought maybe it was because I bought a cheap cable, so I went to Radio Shack and picked up a $70 Monster HDMI cable. I had no intention on keeping it, I just wanted to compare quality again. The new cable made absolutely no difference. Component still looks way better than HDMI.

Am I missing a setting somewhere? Anyone have any suggestions? I'd much rather use one thin HDMI cable than the huge 5-cable RCA that is needed to run component to my TV.

Sounds like your tv has a problem with HDMI. Have you tried any other HDMI sources besides a 6412? If the tv is still pretty new you might try swapping it, or if it is still under warranty have them come out and try to fix it.

On my Sony XBR960 crt set there is essentially no difference between HDMI/component. Which makes sense because this set just converts the HDMI into component internally and then processes it identically. But it sounds like your tv is handling the HDMI separately and in a poor manner.

i don't have another HDMI source to test. the TV is still within Circuit City's return policy period. I just need to find a dvd player or something with both component and HDMI outputs so that I can do another side-by-side comparison.

It sounds weird, because often on LCDs or other digital display technologies HDMI will look a bit better since it doesn't have to be ever converted to analog along the way like component does. I'd definitely check it out on another device before your 30 days are up.

Yeah I know. I have an LCD with a DVI connection on my computer at home and noticed a big difference compared to a standard VGA connection. I had the same hopes for HDMI on my TV, but have been really disappointed. I'm going to check out some DVD players this weekend that support both component and HDMI so that I can do another side-by-side comparison.

Njeske which TV is it? Ive heard this before (I work at CC)

It's the Samsung 32" LCD. Model LN-R328W.

Please post your results, had a customer with the same issue, it was a Samsung 42" Plasma. Said it looked tons worse with the HDMI using the Comcast DVR.

And you're admitting that;)?!?!?!? (Just kidding of course...)

Please post your results, had a customer with the same issue, it was a Samsung 42" Plasma. Said it looked tons worse with the HDMI using the Comcast DVR.

so his experience was that it was the comcast box and not the TV?

well... i went out to circuit city this morning and bought a samsung dvd player. the HD-850 has both HDMI and component outputs. i ran both in a side-by-side picture-in-picture and the HDMI still looks like crap.

guess i'll be returning the TV. :(

i exchanged my p3 box since the fan was so crazy loud. This one sounds like how it should but im still wating for the guide to show up. Its not downloading anything do i have to wait or does comcast need to send a hit to it?

when i exchanged mine it took about 20 minutes to download the guide. comcast didn't hit the box for 2 days though, so for a couple days i had all the premium channels.

If the box was a previously used one, then it needs either a hit from Comcast or you can do it yourself.

mine works fine. The box is as silent as can be, i must have had a bad one. The first hit didnt work, when i called back they sent a different hit, some type of reactivation one and it immediately started downloading. All is fine.

edit, scampa just saw your detailed reply. I wish i saw that before. But instead of doing it myself i called and they did it. That is some valuable info thanks!!

Since I've had my P3 working now for a week, I've had time to compare it to the P2 I still have.

There is a noticeable difference in the look of the analog channels. I think it was reported in this thread previously to look "better" on the P3, but I have to disagree. My P3 produces a blurrier, more smeared out looking analog picture when compared against my P2 on the same channel. It looks like it may be applying some filter or something before digitizing the image - there is less analog noise, almost none, but also there is less detail.


I was one of the posters that mentioned a better picture on analog channels, perhaps the only one. I take it all back. It seemed "better" at first because of some perceived elimination of snow; but in exchange, it seems to have decimated all hint of sharpness, clarity and detail. The box has multiple problems so I'll be trying to get another, but I fear all series III 6412's have "smear-o-vision" on the analog channels. It's so bad that the news crawl on CNN, that looked pretty sharp and precise (for an analog channel) on previous boxes (connected via component) - and now that precision is at the level I used to see on cheap RCA 36" (all for price, not PQ) in the early 90's. HD channels still look good; no better, no worse than before (which is OK).

I wish Comcast had done a better job with their recorder boxes; I long for the reliability of TIVO (just retired so even if they came out with a HD capable TIVO with a cable-card slot, I'd only be able to look at it in a catalog).

Bill, how does your cable picture look if you view your cable w/out going through the 6412?

Some analog channels have more noise (snow) but are sharper; it's still acceptable with the HD monitor. The old 6408 is still connected to the TiVo as it's dedicated tuner and there has been no change in quality (pretty good). I have a TV in another room with no box at all (not HD either) with direct cable connect for the final days of analog cable (!) and some channels are great (Weather Channel, a.k.a. MTV for seniors, looks great, other channels have varying levels of snow, not really bad, no very little ghosting or any interference - in other words very good for analog. But two stairwells down in this apt. complex my friends get inferior pix with deep snow on some analog channels, ghosts on some. Comcast has had their "ticket" for a year and just ignores them (their digital and digital HD reception is fine). I never have figured out who owns the cable running through the project, but I have a feeling no on is going to dig cable runs to fix someone's analog reception.... and my neighbor has extreme channel-to-channel variations. I seem to have more consistency, for example their MTV looks like it's coming from a dipole antenna in the basement, mine looks just fine.

i think my analog channels look pretty good on my p3 box. of course they are stretched and don't look as good as they would on an analog tv, but it's not really that bad. when i first switch to an analog channel from an HD channel i notice the huge difference, but after a few minutes of viewing i don't even notice anymore. they look pretty good to me.

Yes, through the rf and the rca (baseband jacks). I work at comcast and get that question all the time =)

Penywize,

What was the question that prompted this answer? I must have missed it:confused:

yeah... i'm confused about that post as well.

How can I leave the 6412 on, while turning off all other components, with the "all on/off" button?

I was able to disable the Cable Power button on the remote, but didn't mess with the ALL ON button. I don't intend on using it. In fact, I may just disable it.

Can I remap Cable Power to TV Power?

Also, HDMI quality on my Panasonic HDTV Plasma is MUCH better than component on HD channels. Overall, the quality of all channels is better than my old DCT-2000 box.

Finally, RF Out is disabled.

If only the box wouldn't continually randomly restart it would be great!

Anyone had trouble with theirs missing recordings? It's weird it missed a show last night and the night before. Last night it was a show between 2 other shows and both of thoose recorded right. Not to mention it locked up on me last night too. The recording did not have any conflicts, the box was on, and noone was watching tv to have messed it up.

Was the show a rerun?

I have mine set to record Letterman, new shows only, and last week during reruns it correctly did not record them, but this week, with them marked "New", it decided on Wednesday night for some reason to not record it, and the scheduled events showed it didn't plan to on Thu/Fri either, so I had to nuke that series and redo it.

I'm wondering if the phase III software has a glitch - I previously had Letterman scheduled on my P2 for several months without a problem, and just had moved that series to the P3 a couple of weeks back.

Was the show a rerun?

No and it had the 3 red dots implying it would record it. It didnt have the O with the / across it showing a conflict either.

Does the new RF output on these phase 3s just provide a pass through of the cable signal, or is it a modulated output that shows whatever the 6412 is displaying on its other outputs? asked by MR2828 #112

I don't think this was really answered througly. I just set my box up this week and have HDTV going to a HS51 via component but I wanted to keep my SDTV for the kids (and the wife). I was excited about the RF out on the phase III and it does work very well. RF out to a SDTV shows all content with the menues. HDTV is down-res'd to a letterbox and looks great.

Ok - now for my ?

I have a mild interference pattern on the screen (very light line of SSSSs). I'm outputing component at 480p to a sony HS51. If I set the box to 720p (which is native to the HS51) or 1080i the interference pattern is horrible. at 480p the HDTV looks fantastic with the exception of the light pattern that is usually only noticible with solid colors. I have a HDMI cable ordered. should going digital fix this? If not do I need to get comcast involved to try and fix it.

Thanks

I've been watching this thread for awhile and have been thinking about taking my 6412 Phase 2 in for an exchange. I had tried using a DVI-HDMI cable to connect to my Phillips plasma, but I had major sync problems when going from SD-to-HD channels and back again. I had to turn the TV off and back on or switch inputs back-and-forth to resync. After a few hours of frustration, I just switched to component cables and called it "good enough". I had a few other problems with my Phase 2 such as HD recordings pixelating or stopping inexplicably. What pushed me over the edge was when the first 10 minutes of Lost this week was missing the audio (luckily it was on the TiVo upstairs).

The Comcast people here in Denver couldn't tell me for sure or not if my service center had the Phase 3's or not, so I took a chance and made my way to the service center. I was handed a factory-boxed unit - my optimism rose. After I got it to the car I sliced at the tape with my car keys just enough to peek in... damn, wrong end. OK, lets try the keys on the other end of the box... SUCCESS! I see HDMI and SATA ports!

I somehow avoid speeding tickets and accidents on the drive home, push my wife and child aside as I rush for the basement home theather. Sorry, no hugs and kisses, I"M DOING HOME THEATER DAMMIT, LEAVE ME ALONE!!!

Dang, why didn't I run the HDMI-HDMI cable I had bought earlier already!? I hurridly rip open the packaging on the cable, unwide it and spool it down to the pass-through to the plasma. Damn! They thought of 'Ambilight' but why didn't Phillips put the HDMI connectors on the side! After minutes of fumbling I finally Helen Keller the second HDMI port (using the first to connect my laptop occassionally). I'm seriously considering the extra bucks for an articulating mount now... OK, back to the Phase 3...

All cables connected (digital optical, component, HDMI, RF) now power... Yes, it is booting. Turn on the plasma while it boots... component still works anyway. Time to switch... yes, HDMI works the first time! Switch channels to an SD signal... works. Back to HD... works. Yeah! If the DVR works as specified, I'm one happy camper.

So now I move onto the serious business of getting the SATA port to work. Sounds like we're waiting for Comcast for an OS update before we can start adding serious storage to the 6412. I'd like to order things now. Sounds like I want to go for an eSATA-eSATA cable and case with the biggest drive I can afford. Is that correct? It would seem like something like Wiebetech's TrayDock eSATA (sorry, don't have enough posts to put a link in yet) would be a great expandable solution if Comcast ever decides to implement the port.

ejroth,

It sounds like you have a grounding issue. It's probably because you have it connected to two different setups (RF to an SDTV and YPbPr to an HDTV). Try unhooking the RF coax to the SDTV and see if the interference goes away.

If it does you can try to go to Rat shack and find some sort of filter for the RF coax to see if that helps. If it doesn't there are many places that noise can leak through the grounds and cause this. Try also unplugging each cable one at a time and see what happens.

Report back and we'll take it from there:)

macdanife, you sound a littel excited:D!!!

Quick question, does anyone know if the P3 box's HDMI outputs YCbCr as it should or does it just default to RGB for some reason (Motorola/Comcrap's bad SW/FW maybe)? Can someone confirm this who has it hooked up to an HDTV w/ HDMI?

Sounds like I want to go for an eSATA-eSATA cable and case with the biggest drive I can afford. Is that correct? Depends on what type of case you get. A lot of the cases have SATA I ports on the back so you might need a SATA I - eSATA/SATA II cable. That's what I needed. Check the SA8300HD SATA thread (http://www.avsforum.com/avs-vb/showthread.php?t=516559), that'll tell you all the pieces you need. Also if you don't want to put your own together you can also get the Maxtor Quickview drive.

I sure hope Comcast activates it soon, I was spoiled when I had the SA8300, 120GB just ain't big enough.

Just an update and for anyone in the future that may have the same trouble.
(see post #281)
I had a fairly noticable pattern of SSSSs across my screen going from the 6412 to my Sony HS51 projector via component. My HDMI cable came this week and when I hooked it up the pattern immediatly went away (as in theory it should). Picture looks fantastic!!!!! Also the 6412 automatically changed its output to 720p which is native for the HS51.

I was able to disable the Cable Power button on the remote, but didn't mess with the ALL ON button. I don't intend on using it. In fact, I may just disable it.

Does anyone know how to remap the Cable Power button on the remote to act as a TV Power Only? (I do not want to use the ALL ON/OFF feature as that requires holding the button down for a couple seconds).

Thanks.

On my remote (silver Comcast one), the all-on button woks fine. Push it once and you see the various lights at the top flash when they are sending the power-on/off sequence to their respective devices. You don't have to hold it down. I don't know of a way to remap the power button. :)

The Cable Power button for the 6412 remote cannot be remapped.

How can I leave the 6412 on, while turning off all other components, with the "all on/off" button?


AFAIK, despite what Plomaris posted above on this page, neither CABLE/POWER nor ALL ON can be disabled so that using these buttons does not power the 6412 on or off.

The only way to keep the remote from powering the 6412 on or off when ALL ON or CABLE/POWER is pressed, AFAIK, is to block or aim the remote or converter so that the remote signal is not received by the converter. If you really need this function, you might be better off with a third party programmable remote.

Comcast users at least are advised to avoid using the ALL ON button and to avoid powering the 6412 off because the converter is prone to a muting issue after the 6412 has been powered down after only being powered on for a relatively short time, as in less than a few hours. Here's the issue people will have. The box is off. They turn it on and watch for half an hour. They turn it off. When they come back and turn it on again, the audio will often be muted. Pressing the VOL button or MUTE button on the remote does nothing. The muting error can be cleared by unplugging and replugging in the 6412 to AC power. They think their box is defective and call Comcast. The workaround is: don't turn the converter box off!

Is this box any quieter than the original 6412s? I can hear the constant hard drive whir and chatter on my 6412.

Someone report on the noise from this new 6412 (or the lack of noise).

I have two 6412 ph III hd dvr's. The one in my bedrrom just blows and whirls away all day and night at random intervals. The one downstairs I have NEVER heard a peep from, not even a whisper. My friend had a 6412 Howler and could take it, he said he couldn't sleep through the night. He took it back and got another one and was told by Comcast that some have fans and some don't. I haven't heard him conplain so I guess he got a fanless 6412. I would take my 6412 Howler back but it's a pain to unhooked my gear in my wife armoire that I haven't bothered and I learned to live with it...seems not to howl as bad as it did when I first got it a month or so ago.

In response to Runnoft, I was able to remap the Cable Power button to the Info button successfully.

I can't make it any more plain than that. You CAN remap the Cable Power button. As for the ALL ON button, I haven't played with it.

The Phase IIIs have a fan, and this is the 3rd report I've seen that some of the fans are defective and make a loud whirring sound randomly. The first P3 I got did that. So I returned it and swapped it for another one that wasn't defective. Now the fan is pretty much silent.

In response to Runnoft, I was able to remap the Cable Power button to the Info button successfully.

Great!

I can't make it any more plain than that.

Sure you can! You can tell me how you did it. I said "AFAIK", because I haven't seen you or anyone else say how. If you show me how, I'll stand corrected.

By the way, I should point out that I have a Phase II 6412. I assume button mapping wasn't upgraded for the Phase III boxes, but it's possible.

The instructions for remapping the cable power button are NO different from remapping any other button. I don't have the procedures in my head right now, but you can check CJH Engineering for how to remap a button. I think they also have a link to all the codes for the remote. Just map the INFO code to the cable power button. Now if you press power on the remote when in cable mode, you'll just see info.

Oh you doubters. Me too, since I had several times tried --and failed--to reprogram Cable Power-->TV Power. Which does not appear to work. Then I saw the obvious--reprogram Cable Power-->[Something that does not cause trouble but does not turn off the cable box, thereby disabling the Cable Power button].

Why not use Info? It's harmless. Or, if you want to get some mileage out of your Cable Power button, reprogram it to Tuner Swap. Both work just fine.

Some background. I have four 6412s and four Comcast silver remotes (from December 2004). With a family of six and lots of visitors, it became obvious in a short period of trying various remotes that the Comcast remotes were easier to use, programmable to do all that was needed, and--most important--identical, so that cable box control all over the house worked the same way. But no way to avoid accidentally turning off the cable box from time to time.

So I reprogrammed the TV device with ALL of the cable functions--except power, volume, mute, input, PIP controls, and format (TV aspect). Then I instructed the residents to leave the remote in TV device mode, and never push the Cable button. That worked, except for the occasional accidental push. I also reprogrammed the Aux mode to do all TV functions--channel, menu, AV setup, etc.
so Aux gets used only to set up those hidden TV things, and to control PIP when needed. But there remained this annoying accidental turn off of the cable box.

By the way, I am on RCN now, as of April 2005. Kept the Comcast remotes, however, because the RCN remotes--although otherwise just fine--were not programmable and could not do tuner change and skip ahead. Also the Comcast remotes are excellent at not being too picky about aiming. I often bounce the beam off the ceiling or off an opposite wall.

So, to the point. Keystrokes to reprogram Cable Power button to be Cable Info--


Cable
Hold Setup till two blinks
994
Setup momentarily
00044 (change this for other functions)
Power
Watch two blinks (if not two blinks, start over)


If you really want to disable the Cable Power button, use code 00111. This will send a "G" to the STB. The box will not even issue a short blink.

For "other functions", go here
cjhengineering 6412 remote control advanced coding

Try it.

Okay. I am on a roll now.

You can program the device power buttons with total-do-nothing codes, codes that are not listed in the code base. These can be tested before programming with this procedure--

Device Button
Setup ((momentery)
code (0-0-digit-digit-digit)
Watch the device to see if anything happens

So now both the Cable Power and Aux Power do nothing on my remotes.

And, as a result, the All On button turns on or off only the TV. Which is exactly what I wanted.

Thanks Einride! Great ideas... exactly what I was looking to do.

BTW - Do you know what the HD Zoom button is supposed to do? Mine does nothing. I thought it was supposed to allow you to zoom a 4:3 on a 16:9 display. My tv is 16:9 and can zoom/stretch 4:3 to 16:9 on 480i input but not on 1080i. Somewhere in these forums I thought I read that it was possible to zoom/stretch a 4:3 formatted HD channel (like the local news on an HD channel) using the cable remote. I will search some more and see if I can find that info...

Thanks again.

The silver Comcast remotes are multifunction units that work with about two dozen different cable boxes. HD Zoom does not appear to do anything with the available 6412 boxes.

That said, pushing the HD Zoom button will result in a very brief flash from the remote lite on the box. This means that the box recognized and accepted the command, but did nothing. Meaning that the command is, indeed, intended to control the cable box. But probably the functionality is not enabled. Maybe not even in the hardware, just the remote command processing software.

From my observations, when a recognized command arrives at the command processing software, the lite turns on and stays on until the command is executed by the unit. No flash--or perhaps a flash so brief that it is effectively invisible--means the button is not programmed for the device, or the programming code is for the device, but is not recognized by the remote processing software. A very brief flash is as above. A longer flash (say, one quarter of a second up to several seconds) is for a normal command that is being executed.

As for expanding a 4:3 picture on an HDTV channel, my TV can do that. The picture is stretched horizontlly so that a 4:3 image on an HD channel fills the screen (and a full screen picture exceeds the screen). The picture looks the same as a 4:3 SD image on Comcast Sportsnet or ESPN HD that has been stretched at the provider end--that is, it looks ugly and distorted.

A cable box could crop the blank space off of a 4:3 HD image, then expand the result keeping the aspect ratio, but the top and bottom would exceed the screen.

There is no real good compromise that I know of that will work well, although stretching horizontally at least gives you the whole picture and eliminates screen burn-in.

I forgot to mention that I have a Motorola remote that is sold for use with the 6412. It has a layout very similar to the Comcast silver remote, with identical PIP buttons. There is also an "Aspect" buton where the Comcast remote has its "HD Zoom" button.

The Motorola button does the same thing as the Comcast. It produces a brief flash on the cable box. And nothing else.

Nice remote. But not key-programmable.

I don't know if this has been asked and answered yet but:


Has anyone connected the HDMI output to one of the new hdmi switching receivers?

Do you have any HDCP handshake problems connecting the STB to a receiver through HDMI?

Does the HDMI port pass 5.1 audio?

Does anyone know the HDMI version on the STB?


Thanks

I just picked up a Phase III box today and have noticed that the analog channels (< 99) are all displaying blue artifacts on the screen. Based on what I've read in this thread, I'm guessing this is due to the box compressing the analog signal and trying to apply filters to clean it up.

Do you guys think what I'm seeing is a sign of a bad box or a bad signal (meaning box would work fine w/a better signal)?

Thanks,
James

James,

Everyone I have spoken too raves at how much better the analog channels are displayed on the Phase III box compared to the earlier generations. I suspect you have a problem alright.

I recently moved from Directv to Comcast and got a Phase III box. I really like the setup
except that the box seems to cause a humm in my subwoofer. I know it is the box - if
I disconnect the cable from the box the humm goes away. I have both my receiver/DVD
player and Phase III box connected to my TV via component cables.

The tech came in and said it is likely to be a problem with the box - I need to get a
new one from Comcast. Has anyone else had this problem ? Will it go away if I get a
new box ?

Thanks

sam

That hum is usually a ground loop coming in from the coax line. Try going to radio shack and get a coax hum eliminator and try that first because it's likely that it may happen with any box you get, especially if the leak is external to your house.

Have them run a signal check and check the coax with a TDR (Time Domain Reflectometer) also. That will show any bad connections in the line. Make sure he/she checks inside and out of your house.

As a temp solution, if your sub has a three prong power plug, try a 3 to 2 prong adapter ("cheater plug") that lifts the ground and see if that helps. (Use this solution only temporarily as it can be dangerous to do this. It's a potential shock hazard)

Have them run a signal check and check the coax with a TDR (Time Domain Reflectometer) also. That will show any bad connections in the line. Make sure he/she checks inside and out of your house.

Or upgrade to a Digital Audio Cable - no hum - no interference!

Do these boxes have PIP?

The Comcast people here in Denver couldn't tell me for sure or not if my service center had the Phase 3's or not, so I took a chance and made my way to the service center. I was handed a factory-boxed unit - my optimism rose. After I got it to the car I sliced at the tape with my car keys just enough to peek in... damn, wrong end. OK, lets try the keys on the other end of the box... SUCCESS! I see HDMI and SATA ports!




I'm a comcaster in Denver and have a phase II and what to get a phase III. Do you just show up to the service center and "demand" a new box or do you need to get some sort of return/exchange/service number from customer service first? What service center did you go to?

Thanks

Does anyone with cogeco digital cable in ontario have a phase III yet? is it offered by cogeco?

Thanks.

Thanks.

Yes it is. I picked up mine from the main Burlington location about 6-7 weeks ago and it is a Phase 3. The Firewire ports work but unfortunately only 1 of the tuners is supported right now. Cogeco has promised a software update shortly :rolleyes: to bring the second tuner online.

I remember reading a post where someone said that they use their Tivo for the kids shows, to save room for the HD stuff on the Motorola cable box. I'm trying to figure out how to set that up. The Tivo apparently has no tuner and seems to assume that there is a cable box out there, so my original idea of having the cable run directly into the Tivo (splitting before the cable box) doesn't work--I can't change channel. Of course I could get another cable box, but that's another box and more money. I don't want to run the TIVO after the cable box, or the TIVo and the cable box wouldn't "know" about scheduling conflicts.

Any ideas?

Thanks,

Andy

You are wrong, the TiVo does have a tuner. You just have to be happy with the analog only channels. If you want the digital channels on your TiVo, then you will have to get another cablebox.

Take a look at the back of your TiVo, and you'll see an RF input

Im gonna kill my box LOL. Actually it's probably not my box, I think its Comcast... but I lost 810 (NBC HD) today... go to the channel and I get nothing at all. And the irritating part really is the fact I unplugged the box and plugged it back in to see if that might help, and now my box will take 2 days to fully populate the guide. Always takes that long, and that drives me crazy.

Hit "INFO" on the remote and see if the channel bar comes up. If it does, then go to "MY DVR" and start playing something and then go back to live and you should have a pix. This is a known issue with the 6412 and that's the way to get video back.

If that's not the issue and you really lost NBC-HD, then it may be the source and not the cable box's fault, so....never mind;)!!!

That hum is usually a ground loop coming in from the coax line. Try going to radio shack and get a coax hum eliminator and try that first because it's likely that it may happen with any box you get, especially if the leak is external to your house.

I could not find a humm eliminator at radio shack - tried using a pair of 75-300
converters. That did not work. The comcast guy was no help just wanted me to
get a new DVR. So I tried the 3 to 2 prong trick and .. success !!! No hum at
all. I have only my subwoofer connected like this - the rest of the equipment is
connected to all 3 prongs.

Thanks much for the help !!

It is called a " Ground Loop Isolator " Try a Google search.

I have 3 from Radio Shack, all 3 with RCA male & Female ends for R/L Audio

Thanks, couldn't think of the name at the time.

Sam,

Get the one with the RF coax "F" connector and try that first, then if that's not where it's coming from try the other connections like RCAs as scanpa mentioned.

Sam,

This is the one scanpa mentioned:

http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=270-054

I can't find the RF coax one I have used in the past. Maybe they don't carry it anymore? Try an electronics supply house.

AFAIK,

RS does not sell one that has a Any other connector other then RCA, at least till I quit working there. Ground Loop's are found in the Audio cables and Audio Amp stage. At least AFAIK.

Guess I will do a google and look for one with a F- Connector!

Great. I did see that input, and plugged my cable in there directly. But I couldn't find a way in setup to tell the Tivo to use an internal tuner rather than changing the cable box channels (e.g. I saw no option for having no cable box at all). I thought maybe the RF input was for those who want to use coax cable to go from the cable box to the Tivo.

SO the bottom line is I can't get the Tivo to change channels. I guess I should be asking this in the Tivo forums. Sorry about sidetracking things.

Thanks,

Andy

On the tivo go to setup and repeat guided setup

I'm also curious about the HDMI connector and associated firmware. I know that with the SA8300 and its approach to HDMI, connecting it via HDMI to a TV (e.g. Sharp Aquos 45") which does not support DD5.1 causes the SA8300 to shut down its optical/coax digital audio output from Dolby Digital 5.1 to PCM 2.0, something which is not very desirable.

The solution for the SA8300 is either (a) to never use the HDTV speakers and instead "force" the SA8300 to put out Dolby Digital audio via Audio Setup, or (b) to use a HDMI-to-DVI connection to the HDTV instead (which avoids the unintended HDMI audio DD5.1->DD2.0 complication back at the SA8300), and also run a separate L/R-stereo audio cable to the HDTV for "ordinary" HDTV watching via HDTV speakers, and also to force digital audio output via Audio Setup to Dolby Digital so that the optical/coax output is indeed DD5.1 to the external theater surround sound system when present.

I'm curious to know if Motorola's implementation of HDMI for this new 6412 is similar.

Help! It might be.

I'm planning to demo my new system tonight and can't get DD5.1 to work. I have my Starpower 6412 connected via HDMI to my PDP1130HD (no speakers) and my digital optical out to my Onkyo SR600 receiver. No DD out of the Onkyo, it says it's getting pcm. In the cable box audio menu I set it to "matrix" (the choices are mono, stereo, and matrix) but this doesn't help. Any suggestions on how to "force" the DD out? (I guess based on the above I could try component out to the TV and see if that "solves" the problem).

Thanks,

Andy

What is your firmware version? Try using component and see what happens.

Firmware 12.13

Confirmed that I get DD when I hook up the box to the TV with component, but not with HDMI (I occasionally had to power-cycle the TV or the receiver to make it work).

It also seems to me that the HDMI connection is a bit sharper than the component.

So, what to do?

(a) Can I somehow "force" the 6412 to output dolby digital via optical audio out? I don't see how.

(b) DVI-to-HDMI instead of HDMI (I never use the tv speakers)? Then all I need to make that work is a DVI-to-HDMI converter?

(c) What about taking a digital audio out from the TV back to the receiver? Do I understand correctly that the HDMI connection is sending the full digital audio information to the TV as well as the video?

Thanks,

Andy

Yes, this is probably what your problem is since audio is also sent thru the HDMI cable, you will need to send it back from the TV to the receiver. Does your TV have DD output?

When I have had the Audio switch from DD5.1 to PCM via the Optical Digital Audio Cable, I was told to do the following to reset the Digital Audio out,

power off, then press menu within 2-3 sec.

go down to the bottom and select restore All Settings.

(this also resets all Digital Audio Out settings that Comcast End users have no access to.)

then go back up and reset all of your Video out settings.


YMMV, but this has always worked to restore DD / DD5.1 Audio to my Optical Audio Output.

BTW, what does PCM stand for, its the red and white audio outputs, right? Thanks.

YMMV, but this has always worked to restore DD / DD5.1 Audio to my Optical Audio Output.

I don't think my problem is about "restoring" DD. It simply switches off when I plug in an HDMI cable, and switches back on (with power cycle) when I unplug the HDMI.

So, yes, my TV has digital out. But I tried that and it didn't work. Then I looked on the TV menu and the settings for digital audio out were grayed out "Not applicable given your current settings" or something like that. Then, when I disable HDMI on the TV, the digital audio out comes back. So it looks like a catch 22 -- when I use the HDMI, the TV won't enable the digital out. Maybe something to do with copy protection?

So that doesn't work. I guess it's component input for now if I want my HD with DD5.1 from the cable box.

And now, aarghgh, the optical digital out plug on my TV's media receiver box seems screwed up -- it doesn't click in. Sigh . . . Within the first 30 days, but what a pain.

BTW, what does PCM stand for, its the red and white audio outputs, right? Thanks.

No, the red and white outputs are the analog signal outputs. You have a toslink and a RCA digital output that will give you either PCM or DD.

Sorry but that link above didn't make any sence to me.

So are you saying that toslink is DD and coaxal RCA out gives you PCM? Sorry still a little bit confused here. :confused:

You have 2 Digital Audio outputs (toslink and coaxal RCA) on the back of the 6412 & 1 set of R/L Analog Audio RCA Connections.

Both Digital Outputs can do DD, DD5.1, & PCM Digital Audio Modes.

The Analog Audio R/L RCA will only do Analog Stereo & D Pro-Logic Surround.

I checked the manual of the TV more carefully and find that the PDP1130HD does not accept DD5.1 over HDMI and in any case doesn't output it over digital optical when HDMI is enabled.

This cable box also doesn't have DVI, right, just HDMI out? So if I want to use HDMI and DD5.1, so that leaves (a), which I can't see how to do.

If you have dvi on your tv, you could get a hdmi-dvi cable.

Yes, that would work if the hdmi-dvi cable didn't also shut off the digital audio out on the cable box. I don't have any idea whether it is the hdmi plug going in or the hdmi signal going out (rather than dvi) that would shut off that signal . . . I suppose I can test and return the signal if it doesn't work. Now I have to get the digital audio out plug fixed on the media receiver anyway, though.

It's the HDMI signal that changes the audio output. I have a series III and both component and HDMI cables connected, along with an optical audio output to my receiver. When the component input is active, all is well and DD 5.1 is working, no matter if the output is live or recorded. When the video input is swithed to the HDMI input, the audio feed to the receiver suddenly changes to PCM. Change the video back to component and the audio follows suit back to DD.

What do I do to get both HDMI and DD5.1?

Maybe the solution is to go back to a Series II with DVI out instead of HDMI. Is there a DVI out on the series II and does it work?

Yes and yes.

But then I'm back to the much lousier analogue tuner, by many accounts. I've e-mailed Motorola -- maybe there is a firmware or software update.

Just run a splitter and run one line to your TV for analog channels and another to the DVR for all digitals. This uses the better analog tuner in your TV.

I guess it won't help with any analog recordings you make though:( I guess you need to decide what's worth it.

Good idea. I actually already split and run one feed straight to the non-HD Tivo for the kids' analog recordings.

I guess I just hate to have an older box -- just a feeling of not having the latest, though evidently not necessarily greatest. :-) Before I swap out the cable boxe, I'll see if Motorola can come up with something for the phase III. I know from browsing this and other sites that I'm not the only one with this particular problem.

If it means anything, you could get the Sony HDD250 or 500 which has HDMI and much larger hard drives and I think better PQ. It decodes all FTA digital and analog cable channels as well as OTA. This can also make your cable bill cheaper because then you won't have the $10 DVR charge and you don't have to pay for a digital tier or two. If you have digital simulcast in your area almost all, if not all, of the analog channels are simulcast FREE as digital channels. (In my area it is at least. Just pay for basic cable.) It also has cablecard to get any premiums you want.

I get an extra HD channel as well. They have the FOX-HD channel from Philly in the clear and that isn't even listed as a channel I get around here. It does not come in using the 6412. Plus, you get all the digital music channels in the clear.

CC had the 500GB version for the same price as the 250 on their website:)!!!

Just a thought;)!!!

This is quite interesting. I'm glad I didn't opt for a Phase III box when they became available in my area. This HDMI-DD audio issue is starting to become more prevalent. There is another thread here where the member's display does not pass back out the DD signal so he can't hook it to his audio pre-pro/receiver. This problem is going to get even more interesting when the HiRez DVD formats come to market.

To tell the truth I didn't think these cable boxes had this problem as I haven't seen too many posts about it.

I don't know if this will help but since HDMI carries both audio and video and the component connection carries video only, is it possible that the 6412 senses the HDMI connection and redirects DD 5.1 to HDMI. When the component connections are active it knows it has to send the DD 5.1 elsewhere so it sends it to the optical audio connection.

Yes, that sounds exactly like what's happening:(

This discussion is unnecessarily confusing. Just connect the 6412 III to your tv/display with HDMI, and then connect the 6412 III to your AV receiver with a Toslink or Coax digital audio cable. You will get 5.1 audio. (Mute the TV's speakers and forget about them!)

Millerwill, you dont understand the problem i too just traded my phase 2 for a phase 3 do to a new panny plasma with hdmi, it will stay in DD as long as i stay on hd channels, once i switch to any SD channel it switches back to pulse modulated, very annoying to say the least.
A new firmware is needed badly!!
I use a optical toslink from the 6412 to my yamaha receiver.\
Never had this problem with my phase 2 box and a dvi connection.

Well, you may be right, i.e., that I just don't get it! I have my 6412 III connected to my Sammy hlp6163 (until my new Mits arrives), HDMI (6412)-DVI (Sammy), and a Toslink digital audio from 6412 to my Pioneer AVR. One hd channels that output 5.1, my receiver automatically detects it and delivers it; otherwise I have it on DDPLIIx/Movie. No SD channels output 5.1, so the AVR outputs DDPLIIx for them (or sometimes I have it set to produce NEO 6 Cinema). Is there something not right about this?

I think the problem arises with a HDMI>HDMI connection. You have a HDMI>DVI connection. The device at the receiving end tells the sending end what audio to send and what outputs to shut down on the sending end. I think..I don't know enough about the intricacies of the HDMI protocol to know for sure, but I do know that there is some potential audio issues with HDMI. Especially when it comes to the new audio formats with HiRez DVD. And it seems there are some quirks with displays that have audio output/speakers.

I got a solution. HDMI negotiates resolution and audio between A/V components, right? Then go back to DVI w/o changing the box. Get a HDMI -> DVI converter and then DVI -> HDMI... HDMI -> DVI "interface" does not convert anything so there will be no loss but the audio will be gone from the HDMI output end of this setup, which in theory, should force the MOTO to deliver digital audio through other ports instead....
Complicated? Maybe, but still easier and more appealing than getting an older box just for the sake of having a DVI interface..... I believe that HDMI is too smart for the real world, giving too much control to software running on components (HDCP etc.)...

Good luck:)

Well, I guess I will find out, since within the week I will be replacing my Sammy 6163, and its DVI input, with a Mits 73727 and its HDMI input! So will then be going HDMI-HDMI from the 6412 III to the Mits. I hope you guys are all wrong!!!!

I really don't do anything other than hdtv through the 6412 and dvd's from a Pio 59avi (also to be connected to the Mits HDMI-HDMI), and both 6412 and Pio dvd player will be connected by digital audio cables directly to the AVR. Am I in for trouble?

I checked the manual of the TV more carefully and find that the PDP1130HD does not accept DD5.1 over HDMI and in any case doesn't output it over digital optical when HDMI is enabled.

Wow I can't believe that, how old is this TV? I thought all HDMI connections were DD 5.1 compatible? I thought digital was the future. Interesting.

I hope we're wrong too.. :D Hopefully it is a case of some buggy equipment, but, without delving deep into the HDMI spec, I think the way it's been reported here as operating is the way it's supposed to operate.

Please update us when you get your new display. :)

The problem is not with HDMI, but that the tv doesn't pass 5.1 through to the AVR; this is true even with this year's 1080p sets. To get 5.1 you have to send the audio directly from the source (stb or dvd player) to your AVR via a digital auido cable. Still connect the sources and the tv via HDMI, but this will only be for the video. (Mute the internal speakers of your tv.)

Most of my SD ch have DD2.0 / DD5.1 Audio, Due to all Analog Ch are now simulcast in digital.

Before DS started, had a lot of Mono Ch. SCI-FI for one. Now that SCI-FI is DS, the Audio is DD2.0 and sounds great..... :D

When the component input is active, all is well and DD 5.1 is working, no matter if the output is live or recorded. When the video input is swithed to the HDMI input, the audio feed to the receiver suddenly changes to PCM. Change the video back to component and the audio follows suit back to DD.

This is the clearest explanation so far of what is going on. I have some details to add.

I just swapped my Motorola 6208 for a 6412 phase III (Platform built June 21,2005; Firmware Version 12.18) and I encountered the HDMI/ PCM problem. The nature of the problem I encountered was that one of the tuners gives Dolby Digital (2.0, 5.1) output through toslink or coax from the Motorola box. The second tuner gives only PCM (44 kHz stereo like a CD). Furthermore the output from programs stored on the hard drive is also PCM.

I have a Sony KDS-R60XBR1 SXRD rear projector that I've just finished reviewing. It has HDMI digital video inputs as well as component (YPbPr) analog inputs. My preamp is a Sony E9000ES which displays the type of digital audio signal it is receiving. I am in the midst of testing some Gefen digital switchers. One of these is a 4x1 DVI switcher, a second has 4 DVI inputs to one HDMI output with separate digital audio input/output (toslink and coaxial), a third is strictly HDMI with 6 inputs and 2 outputs. So I tried a lot of combinations.

1) If I unplug the HDMI cable from the Moto 6412 and use the swap function, both tuners and programs on the hard drive revert to Dolby Digital sound output.

2) Just plugging in an HDMI cable has no effect on the DD sound, as long as it is not connected at its other end.

3) If I plug in an HDMI cable from the Moto straight to the Sony RPTV, there is no effect until I switch to display the HDMI input. Then the sound goes back to PCM on one tuner and replay of recorded programs. The other tuner stays as DD output. There is no change, no matter what things I change for sound in the Sony TV menus (speakers off/on, Sound advanced/not, etc.). There is also no change no matter what changes I make in sound setup for the Motorola box. I tried all the things from the onscreen menu. I also tried reset from the "power off" menu. Furthermore I tried a complete reboot by unlugging the Moto. Nothing changed.

4) I also found that just plugging the Moto into the Gefen 6x2 HDMI switcher or the 4x1 HDMI to DVI switcher (with no cable plugged into the switcher output) caused the reversion to PCM on one tuner and recorded playback.

5) I plugged the Moto into the 4x1 DVI switcher. As soon as I plugged in the HDMI cable from the TV (via an HDMI to DVI converter block) the digital audio signal reverted to PCM.

6) In all cases where I got PCM from one tuner and the hard drive if I unplugged the HDMI cable to the Moto box, then swapped from the PCM tuner to the DD one, the condition was corrected. Now the other tuner would also be DD and programs played back from the HD would be DD.

The problem as said above is a HDMI to HDMI connection, i was thinking with my Panny PM50u theres a analog audio in next to the HDMI connector if i go in the PM's menu i can set the audio to analog, which ive tried before and you hear no sound, if i do that it might trick the Moto 6412 into thinking theres no sound needed, i will try tonight to keep you guys posted.
Once you set the audio in the 6412 to DD and change the channel it goes back to PM sound.
I could care less about having DD sound go into the plasma as it's just stereo anyway, i use a Receiver for the DD audio

Thank you Bill!

I sat down with my modest system last night and went through the routine, trying to figure out what was happening at my house with the 6412 vIII HDMI->HDMI, DD5.1 vs PCM issue.

My setup is more modest than the one reported by Bill Cruce. But the results are much the same.

Sony KD-36XS955 TV, Onyko SR702E Receiver

Digital Optical hookup from 6412 to receiver, HDMI->HDMI hookup from 6412 to TV. Component output from 6412 through receiver to TV.

Began by Power Off->Menu and Reset to Defaults to reset all of the audio on the 6412.

Selected program on INHD2 that was broadcasted in DD 5.1.

With the 'power-up' tuner and TV on HDMI, DD 5.1 went to the receiver via optical.

With the 'power-up' tuner and TV on Component, DD 5.1 went to the receiver via optical.

With the 'alternate' tuner and TV on HDMI, PCM went to the receiver via optical.

With the 'alternate' tuner and TV on Component, DD 5.1 went to the receiver via optical

With a prior recording of INHD 'Tuneup' and TV on HDMI, PCM went to the receiver via optical.

With a prior recording of INHD 'Tuneup' and TV on Component, DD 5.1 went to the receiver via optical.

Switching the receiver to the optical output of the TV did no good. The receiver did not see an optical signal from the TV even when it was on the HDMI input.

LeRoyk, go in your TV's audio settings for HDMI and turn it off or to Analog see if the DD 5:1 stays on, it's the moto's detection of HDMI audio thats screwing it all up.

The Sony publishes the same configuration over HDMI whether the speakers are enabled or disabled. Mine have always been disabled. And the advertizement is the same for both tuners in the 6412. The Sony doesn't know which I am using, but the 6412 seems to care.

The 6412 doesn't even care if it is a Sony TV. In fact it doesn't seem to care what it is if it smells like HDMI. If you look at my experiments (#4), simply plugging the 6412 into a Gefen HDMI switcher caused the reversion to PCM on the alternate tuner and previously recorded programs. This was with NO HDMI cable plugged into the switcher output. I don't know what the HDMI switchers send back down the cable but the 6412 was satisfied that it saw an HDMI device. (I'll contact Gefen and find out what the switchers are doing and report back here if they tell me anything).

Well it looks like Moto needs a firmware update!!, no way else around this problem!
When looking at there website all technical is directed to your cable provider.....like they really know anything!!
I want to call Cox but i'm sure they dont have a clue of this problem.

. . .

5) I plugged the Moto into the 4x1 DVI switcher. As soon as I plugged in the HDMI cable from the TV (via an HDMI to DVI converter block) the digital audio signal reverted to PCM.

Good to know I'm not alone.

Does the problem manifest with HDMI-DVI cables? Bill's experiment #5 would suggest "yes". There is an apparent contradiction with this one:

One way to reconcile would be that millerwill is seeing it live through tuner 1, while the problem manifests on the second tuner or off the hard drive (something I didn't test as I pretty much only watch recorded).

I may try to pick up an HDMI->DVI cable myself to try.

There isn't really a contradiction. As noted earlier, millerwill's connection is from the Moto's HDMI output to a DVI input on a Samsung TV. Thus there is no HDMI signalling at all. What I connected was essentially HDMI > DVI >switch> DVI > HDMI. I can only surmise that some signal from the HDMI receiver is being passed back, even through a DVI connector.

It would still be worth it for someone to test a completely passive (no switch in between) version of the above connections, e.g. HDMI > DVI >HDMI

I just got 6412 phase 3 HDMI out cable box from Comcast in Phila. Pa

I set the power off menu to 1080i and 4:3 off

When I tune in some stations I hear a pop sound from both speakers. Now this does

not happen to the same stations if I go back to the station! This does not happen in RF

mode or audio out from the white and red jacks, only through HDMI. This happened to me

when I had a Sony DHG-HDD500 DVR and the output format was set to Auto HDMI!

Changing the output format to 1080i stopped the popping sound! Like I said I made sure

output format was set to 1080i. Unless it really is not! Also I hear this pop now when I

rewind or hit play or live but not everytime. Any guess?

the "Official" fix for this 5:1 DD sound problem is firmware 12.22 so everybody including myself stop trying to boot/reboot/adjust/hookup....etc etc
i'm back to component until i get a firmware update!!!

I had a popping problem with a coax run between the 6412 and my B&K Ref 50 preamp. It was obvious in that the problem occurred when I switched to a different cable. If I were to speculate, I'd say that the "new" cable was not intended for digital (probably not shielded well enough). When I switched to one of the orange Radio Shack cables that's sold as digital coax, the problem went away.

To experiment, don't use HDMI for audio. Use a digital coax cable for your sound and see if the problem goes away. If that works, then you might want to see if better shielded HDMI cables are available.

I am having a problem with My phase 3 6412. I have a samsung HD tv and when I hook up the HDMI cable it says I have no signal. I have the box set to 1080i and 480i. when I hook up the component cables the HD works just fine. When I switch to the HDMI it has a green haze and then disappears saying no signal weak signal. i don't know if the HDMI cable is bad or the box is bad. Anybody had a similar problem?

Guys please remember that each Firmware is desogned by Motorola & then tailored by the Cable Co. for that individual Head End configuration and needs..

Current Comcast Cable Firmware for the 6412

09.12
09.15
09.17
09.19

Beta Testing

09.21


The Phase 3 has firmware

10.xx

I thought that number seemed sort of high. Any word on a Comcast FW fix?

Since the HDMI signal includes the video and DD5.1 in one cable shouldn't the TV sets that receive it be passing the DD5.1 out on their SPDIF or optical outputs as well? If they do then you could just connect one digital audio cable from the TV and if you switch from OTA to the 6412 no AVR audio switching would be needed.

I don't yet have the Phase III box but this is what I would be trying to run since I use both OTA and 6412 under control of NetCommand on my Mits 62628.

Can someone check this? If it works I'm going to exchange my Phase II box as soon as I offload the HD movies I pulled down :D

I just checked the firmware on my 6412 III, and it is 12.18. Not the 12.22 that is supposed to 'totally FIX' the HDMI problem, but getting close. I haven't received my Mits 73727 yet--still have a Sammy 6163--so I'm connected HDMI (6412) to DVI (Sammy); as soon as I get the Mits (which I hope will be soon), I will be connecting HDMI-HDMI.

Im located in Northern California and my 6412 III has 12.18 firmware also.

Is firmware released in a sequential manner. .19, .20, .21, .22? If so, we may have a long wait. We may have one either way. I presume the firmware is downloaded to the box automatically over the cable when its released?

For a previous poster. The HDMI DD5.1 problem can not be solved by using DD outputs from the TV because on my panel, at least, the digital outputs are inoperable when HDMI inputs are used. My panel is the new Pioneer Elite 1130.

Yes, I think firmware upgrades are loaded automatically (usually over night). And I saw in another thread that UCSB (also located in the Bay Area) has 12.18; so it seems we're are in the same boat in this location.

I will call the Comcast Head End Mgr. And ask him about the phase 3 F/W.

He is the one who told me it is in the 10.xx range. We do not have any of the phase 3 boxes in my area yet.

They have placed a order for those new Digital Only STB However. Since all of our Ch are Digital, I plan on getting one of those Digital Only boxes w/ the reported 300gb HD They are half the size of a 6412 STB and jet black in color. (anyone with pictures yet or model info?)

Should be out Jan 2006 :D

I guess they feel that is large enough for people to record shiws one day and then watch & clear them out the next day before you record more shows :eek:

The DVR was never intended for people to archive shows for any length of Time!

I feel like there should be quad tuners, built in signal amp., Duel 500+ gb HD with active external HD support. But thats just me!

I can fill my 6412 up with 8 60 min HD shows almost every day! Thank god the Reality CBS/NBC shows are not yet in HD.

Could this be a setup problem with your panel? It makes no sense for HDMI to terminate the DD5.1 on a video device and not have a way to transfer the audio component to a 5.1 audio system. I doubt your panel has a 5.1 speaker system built in.

Actually, 300Gb would probably be plenty for me. I don't keep anything for more than a few days, a week at the longest. I was just surprised that they were actually bringing something out larger than the current 160Gb as Comcast seems to be more focused on VOD.

But yeah, the monster you spec'd out would be nice too!!

It's a bug in the current FW for the Phase III box apparently. Read back about 2 pages.

Yeah, I've read the whole discussion but I think it is a feature in the 6412, not a bug. Users (millerwill) reported that it sends the audio through the SPDIF when the video connection is HDMI-DVI but when HDMI-HDMI is used the audio only goes through the HDMI cable. Why would the Mot engineers do that unless they expected users to pick up the DD5.1 from the TV SPDIF?

Enabling DD5.1 on the 6412 SPDIF when a HDMI-HDMI connection is used would be a new feature, not a bug fix.

I dont believe its a setup problem on the 1130. I believe there is a post earlier in the thread that describes the problem with the 1130 by another user.

In the PVR forum is where others reported firmware 12.22 fixed there DD 5:1 problem.
I went at lunch time to my local Cox and they said theyt are testing out "beta" software, as said above all firmwares are tailored to there equipment and they have to be 100% positive it will not effect other area's.
Also i called Cox and talked to a upper tier tech and he said prob not till after new years for my area...GRRR
So it's back to Component for now!!
Well at least i got my HTPC hooked back up on HDMI!

Im located in Northern California and my 6412 III has 12.18 firmware also.

I'm located in Montgomery County, Maryland (DC suburb). As I mentioned earlier when reporting details on the DD/PCM problem, my 6412 phase III (Platform built June 21,2005) has Firmware Version 12.18.

Hey, me too (to all of this, except possibly the build date.) Are you RCN or Comcast?

Since the HDMI signal includes the video and DD5.1 in one cable shouldn't the TV sets that receive it be passing the DD5.1 out on their SPDIF or optical outputs as well? If they do then you could just connect one digital audio cable from the TV and if you switch from OTA to the 6412 no AVR audio switching would be needed.

The HDMI source (Moto 6412 in this case) is supposed to send A/V signals as requested by the receiver (TV in this case). If the TV has stereo speakers it might request a stereo signal (it could specify DD 2.0 or PCM). If so, that is all that will be available on the TV digital audio output. It would be more logical for the TV to request a DD 5.1 signal then downmix this to be suitable for its stereo speakers. But since this would require a litlle more circuitry, some TV engineers might avoid this to save money. So this could vary from TV model to TV model.

Worse yet, the source should be able to distinguish between what audio is sent to the TV over HDMI and what audio is needed on its own separate digital audio outputs. This is where the Motorola 6412 is screwing up. And sorry, I think this is a bug not a feature.

Thanks for the reply. The HDMI spec confirms that the sink device (TV) is supposed to announce its capabilities. Sources (6412) are supposed to read the sink's E-EDID and deliver only those audio and video formats supported by the sink. So I agree this is a 6412 bug.

That said it is still possible that some TVs would announce DD5.1 capabilities and that this would be passed through to their SPDIF output.

I have seen posts in various threads from people who have the same problem I do - VERY slow responses to commands from the remote (or even if entered directly from the box itself).
Like others, the commands will be held for 20 seconds to 2 minutes or more and then "run" rapidly in succession.

Do tthe "phase 3" boxes fix this? Is there a fix for this on older boxes? Does it just affect some boxes and not others? I didn't notice this until a couple months ago. It has really gotten bad - almost to the point where I am afraid, sometime, to enter a FF or skip command in fear that it won't jump ahead until the commericals are about over - and then skip thru the program - then having to "backup" and wait for the backup command to take hold.

...mike

I noticed the same slow/no response to remote commands on my Phase III box recently, and I figured out what it was in my case: I had the box hooked up via both HDMI (via DVI adapter) and component (to do some A/B testing) to my iScan HD, which is not-HDCP compliant. While this shouldn't be a problem, I think it was causing the box to go into "handshake hell" and become unresponsive to commands. The instant that I unplugged the HDMI connection, everything was back to normal.

I'm new to the HD world having just purchased my first DLP last week! I've learned a LOT reading the various threads in this forum - thanks for all of the info!

I'm in Denver, on Comcast with the rev 3 Moto 6412. I have HDMI connected to my TV and optical audio out connected to my AVR. However, I cannot get the optical output to work. My AVR senses nothing coming into the optical input. I had my Dish PVR connected to my AVR with optical so I know it works. If I connect coax digital from the Moto to my AVR I get DD5.1 just fine.

Anyone heard of the optical output not working on the Moto 6412? I can't find any settings to "enable" it and I've read where several of you are using your optical output successfully.

To add to the "HDMI/DD5.1 issues" conversation - when watching an HD channel broadcast in 5.1 with the TV set to the HDMI input, I loose 5.1 as soon as I pause the program. I have to switch channels and come back to the one I was watching to get 5.1 back...very annoying.

Thanks,
Rick

Read back in this thread a few pages, there a plenty of posters with the same thing. It will apparently be fixed in a firmware update. You should be on 12.18 and the fix is in 12.22. I don't know if we have any updates in between or not.

Try this, unplug your HDMI and use component cables instead. If your problem goes away, you've got the same problem everyone else using HDMI has....

It seems that the HDMI, when in use, disables the optical and coaxial digital 5.1 signal. Do you have your AVR digital set to enable both DD and PCM? That is a requirement in this scenario.

This was posted a couple weeks back but never got any answers:

I don't know if this has been asked and answered yet but:

Has anyone connected the HDMI output to one of the new hdmi switching receivers?

Do you have any HDCP handshake problems connecting the STB to a receiver through HDMI?

Does the HDMI port pass 5.1 audio?

Does anyone know the HDMI version on the STB?

Thanks
I have a little info on the HDCP handshake question, but that's about it. First of all, I have been considering the Denon AVR-3806 receiver due to it's HDMI switching (and analog to HDMI transcoding) feature. There is an AVR-3806 owners thread over in the amps, receivers, and processors forum that I've been following to see how well this feature works. The bad news is that the phase 3 Moto 6412's do have HDCP handshake problems with the Denon receiver. I'm not sure if that's case with all the new HDMI switching receivers, but if you read the Denon 3806 thread you'll find that what most of those users have to do is run 2 separate HDMI cables to their TVs, one for the Moto box and one for everything else (via the Denon receiver). For me that's a deal breaker because I use the Moto box and my only reason to get an HDMI switching receiver is to improve video quality (over component) while still keeping everything on one cable to the TV. You may want to look into the individual threads for each of the new HDMI switching receivers. The Moto 6412 is so common that I'm sure each thread will have at least a few posts about whether there are HDCP handshake issues or not.

I'm not sure if the HDMI port on the phase 3 Moto box passes 5.1 audio because I'm a bit confused by the recent discussions (maybe I read too fast and comprehend too slow). It seems that there are problems when connecting the Moto box via HDMI out to a TV (either with a DVI or HDMI input) for video and trying to use the digital audio out (optical or coaxial) to a receiver for 5.1 audio. There is a bug in the phase 3 Moto boxes that disables the digital audio outs (both optical and coaxial, I think) when the HDMI output is connected to a TV. I'm not sure, however, if anyone has commented yet if the HDMI passes 5.1 audio for use with a receiver equipped with an HDMI input/output, in which case you shouldn't need a separate optical or coaxial digital cable from the Moto box to the receiver for audio. If anyone has tried this please comment!

I am also unsure about what HDMI version the phase 3 Moto 6412 has (1.0, 1.1, etc.) so if anyone else knows please post it.

For me personally, I'm just going to be content with component video for now until all this junk with HDMI gets worked out. It seems there's just too many bugs with different pieces of equipment, such as the new 6412 and the Denon 3806, for me to dive in. I currently have one component cable going to my TV, using a Denon receiver to switch and transcode all video inputs to that one cable. Until I can do that with HDMI using the new Moto box, I'm definitely going to wait this one out. It just seems that HDMI is a huge headache right now for what I'm wanting to be able to do.

I have a PIII 6412 with Comcast in MA. It is connected by HDMI to my panny 50 7UY (industrial, no connected speakers) and by Optical to my yamaha rx-v2500.

I have experienced issues similar to ones described earlier by Bill Croce where the default audio signal is 2-channel PCM however I do receive occasional DD5.1 signals depending on the broadcast. All shows recorded on the hard drive (irregardless of source signal) are replayed in 2-channel PCM.

Bill mentioned that the DD vs PCM signal changes depending on which tuner is used. I have not specifically noticed this but I have noticed that sometimes a show will be in 5.1 and other times PCM. (i.e. MNF two weeks ago was PCM, this week DD5.1) I am now going to pay attention to which tuner I am using (and switch between them) to see if my problems mirror his post.

I look forward to a firmware upgrade from Comcast but I am not holding my breath and will probably switch over to component for now.

I have tried a couple of the new HDMI switching receiver's with the Moto 6412 Phase III box to no avail. My problem when connecting everything up through the AVR is that audio gets passed but not video. I started with the JVC RX-D702B HDMI switching receiver and then tried a Denon AVR-3806. Both have had the same problem.

I know the cables and the capability to pass the video signal from the AVR to the TV are there because I have a DVD player with HDMI out that connects through the AVR and to the TV just fine. I can also connect the 6412 directly to the TV using HDMI without issue as well. I have not paid as much attention to the format of the audio signal while using these connections because I have been obsessed with getting the video to work.

I am going to try one more AVR, the Yamaha RX-V2600. That unit should come in today or tomorrow. I honestly don't have much faith that this unit will correct the problem but for some reason the guys at Ultimate Electronics think that it might.

I just dropped a bundle on a new home theatre system and have to admit that I am very disappointed in the whole high definition/HDMI technologies. Has anyone else found an AVR with HDMI switching that works with the 6412?

Well, that's two down now! Those who want to use the P3 Moto 6412 with an HDMI switching receiver are running out of options fast!

I am going to try one more AVR, the Yamaha RX-V2600. That unit should come in today or tomorrow. I honestly don't have much faith that this unit will correct the problem but for some reason the guys at Ultimate Electronics think that it might.
I'll keep my fingers crossed. Did the guys at Ultimate Electronics give a reason why it would work with the Yamaha RX-V2600?


I just dropped a bundle on a new home theatre system and have to admit that I am very disappointed in the whole high definition/HDMI technologies.
Actually there's no problem with HD, just with using HDMI as a video transmission medium with certain devices. Just use component cables and be happy for now!

I have tried a couple of the new HDMI switching receiver's with the Moto 6412 Phase III box to no avail. My problem when connecting everything up through the AVR is that audio gets passed but not video. [...] Has anyone else found an AVR with HDMI switching that works with the 6412?

If you don't find an AVR that works, I would suggest going with a separate HDMI switch. That way you can select an AVR for its other qualities. Gefen (http://www.gefen.com) makes a ful line of digital video switches, including several that separately switch HDMI video and digital audio. They aren't cheap but they claim to be HDCP compliant and to carry up to 1080p video.

Can someone start a new thread as soon as SATA starts to sing? I am upset after wasting time going through these many pages only to find out she is a no show.

Were did you see that the new 6412's are jet black? All the info I saw they were still silver.

I will call the Comcast Head End Mgr. And ask him about the phase 3 F/W.

He is the one who told me it is in the 10.xx range. We do not have any of the phase 3 boxes in my area yet.

They have placed a order for those new Digital Only STB However. Since all of our Ch are Digital, I plan on getting one of those Digital Only boxes w/ the reported 300gb HD They are half the size of a 6412 STB and jet black in color. (anyone with pictures yet or model info?)

Should be out Jan 2006 :D

I'll throw this into the mix, since there are still some folks thinking about upgrading from an older 6412. I have a P1, I suppose, firmware 9.17, around the first of the year from RCN before Comcast DC had any 6412s available.

I just replaced my HTIB (lost the remote a few months ago) with a Samsung HT-P38. During the installation I cleaned up the cable tangle, including replacing five pounds of five-conductor component cable with a DVI cable. All worked well, until I noticed that the HTIB (on an optical feed from the 6412), was indicating a stereo audio signal from the 6412 on all channels. Also, the DD and 5.1 sound indicators were missing from the info screens on channels where they should have been.

The DVI cable I used was a DVI-D, commonly used for connecting computers to digital monitors. I changed that out to a DVI-I cable and the missing DD and 5.1 sound problem went away. No HDMI involved here.

So I checked some previously recorded programs to see what I got. I got DD 5.1 sound out, but no indicator on the info screen. I recorded a fresh clip with DD 5.1 sound, and got the same result. Is there a sound indicator on the info screen for newer 6412s? I do not see a place for an indicator on my info screens.

It seems to sometimes only show the DD, DD5.1 emblem on Turner#1, I have never seen the emblem on Turner#2, however my Audio Device tells me everything about the Audio.

Under 09.19 It used to show HD on the info page for HiDef programs, but since we went to 09.21, it no longer shows that either. However it does show a large On Demand Popup above the info bar if the show your watching also has a episode or other content available via VOD

I think they are doing quite a bit of testing, while getting ready to test the new Iguide/Tivo software, that will be out in July 2006

I did a quick search on a DCT with 300 GB HDD, and couldn't find anything.
I guess this is just verbal news?
Then it will be a wait until Motorola releases them.
About when will Comcast be having these available?

Has anyone using a P3 Moto 6412 actually tried this? Does a box exist that takes an HDMI input and outputs video and audio separately? If so, would that be a way around this problem since you wouldn't be using the audio out from the P3 Moto 6412?

The DVI cable I used was a DVI-D, commonly used for connecting computers to digital monitors. I changed that out to a DVI-I cable and the missing DD and 5.1 sound problem went away. No HDMI involved here.

Well, sure enough, my sound problem went away with a cable change, but, as you noted, the audio tag shows on only one tuner.

Also, as you say, this display problem is only cosmetic and is not reflected in the actual sound output.

Same issues here overall, DD 5.1 was not working if I use the HDMI cable, the one tuner never shows DD also.

Other issue is the remote, actually it's the box not the remote, it has major issues detecting what the remote is sending, I have to usually point it AWAY from the box for it to work, both with the Comcast remote, and my Harmony remote.

Very entertaining, when I did the procedure above to clr and reset the STB I now have 6412 that everything looks green and purple on. That can't be good.

Lesson, never mess with something that is working. Any thoughts?

First check your cables in the back, one of them might have come loose!

same with the TV.

otherwise try the following to reset the video settings on the 6412.


power off, menu, " restore original settings", then re do all video settings. Power off, power on.

See if that fixed it for you.

We can get those Gefen switchers if anyone's interested in them? Contact me for details.

I'm curious...What are those of you who own the new 6412 doing about the HDMI audio problem. Are you opting for better video quality via the HDMI output, at the expense of losing DD5.1 capability, or are you using the component video output of the 6412 instead so you can still get DD5.1 audio until this issue is fixed with a firmware update? Have any of you had success running the HDMI output to your TV and then a digital audio "pass thru" output from your TV (if it's equipped with one) back to your receiver for 5.1 audio?

I thought that things did work OK (with HDMI into the tv, and digital audio directly to the AVR) for having 5.1 surround if one simply watched hdtv and did not switch tuners or record via the 6412's dvr. I seem to remember some posts of UCSB to this effect, but I could be mistaken.

myapplebuddy,

Took the easy way out, switched the Harmony remote to select composite input instead of HDMI for DVR playback. DD / DD 5.1 works like it did when I had a phase II box, the visual is missing at times, but the output is ok. My TV a Sony KD-36XS955 does a little better job on HDMI, but I missed out on the audio. When Comcast updates the firmware to a level where the HDMI/DD problems are fixed, I will switch back to HDMI on my Harmony remote.

As reported earlier, passthru did not improve over PCM with my TV. I don't think it will ever ask for DD 5.1 in the HDMI handshake, it has stereo speakers plus a built-in sub that are always disabled.

Dropped back to component video. Best balance, good sound and picture. I prefer the HDMI video, but the improvement is not worthwhile given the really irritating sound problems.

Yes, that is correct. But, what DVR owner can give up watching recorded shows or even pausing a live recording. These are much bigger problems then just stepping back to component video. If you still want a digital connection, the IEEE 1394 output seems to be working correctly. I have my 6412 III connect the my Samsung 1080p via the 1394 (D-Net on Samsung). It works, but overall component video is better because you can't see any of the on screen messages in 1394 mode.

True - that's the main reason to get the 6412 DVR! Are there any HDCP, audio, or any other issues with the DVI output of the phase 2 Moto 6412's? If not, are some of you with the new phase 3's trying to get your hands on an "old" phase 2 box until these issues with the phase 3's are dealt with? I have a phase 2 box but I'm limited to the component video output until my new Panny TH-50PHD8UK plasma arrives next month. :D

I'm sitting with the Phase II box and component although my Mits 62628 supports HDMI. I'm thinking the only reason to switch to a Phase III right now would be the better SD quality that some have mentioned.

No ... at least I didn't find any on two Samsung DLP's.

Yes, I think better SD PQ is the main reason you might want to change.

Has anyone had the HDMI port just stop functioning on this box after a service upgrade? I called Comcast and upgraded my package to Platinum on Friday, after which my HDMI port now no longer outputs to my Samsung HLR5067W. It was working since Tuesday after I picked up the 6412 till then. Output is fine over component. I thought it might be a HDCP handshaking problem, but for the life of me, I cannot get it to work. It just keeps saying "No signal or weak signal".

Any thoughts? I'm probably just going to swap this box out for a new one, but still, why would this happen?

Make sure your HDMI cable is securely plugged in.

It is, trust me. Not a cabling noob =)

It is, trust me. Not a cabling noob =)

Unplug the power, let set, and then plug back in ... the DVR will reboot and may clear the problem.

Did that also. Tried different power up sequences with set and 6412. No Joy.

Check your DVR settings ... with DVR off, press MENU button on the actual BOX. 16:9, 720p, etc.

Those are correct as well, 16:9, 720p, 4:3 480p. I've reset the defaults and reconfigured several times. It as though the HDMI output just stopped working, really irratating. The PQ was really nice over HDMI too. As I said before, I'm going to swap this 6412 out for a new one, but it just makes no sense that the HDMI port would stop working for no reason.

Firmware is 12.18, which I've read in previous posts that there is an upgrade out there to 12.22. Not sure if that would correct this issue or not...

I would take your 6412 down to the nearest Comcast office and exchange it for another one.

Sounds like some eeeerrrrrie things are happening to Jaylucky's box. It's Halloween!!! :p

I have a phase III motorola dvr. How do I find it's firmware version?
Thanks for any response.
knpm

Has anyone seen the new user guide or installation manual for the 6412 Phase III? Motorola's web site still has the old model, with DVI and no SATA port.

Also, to see the firmware version, try this (I hope it works): Power the box off and hit SELECT on the box immediately. Use the channel down button on the box to go to D08 and hit SELECT. You should see the version number there. Push POWER to exit.

Here's a fast way to see firmware and recording space/time left
Push menu button..........highlight secondary audio.....................then push DOWN button then B,then UP button then B again, the menu will come up,hit exit button to exit.
No need to turn off DVR first.

Where do you see secondary audio under menu?

When you hit the menu button you get a grey box, down like 3-4 items is play secondary audio, just leave it on there, then press the down/B then Up/B buttons, then a screen pops up showing you the firmware and hours/gigabytes left...real easy dude!!
When i get home in 2 hours i'll verify it....even paste some screenshots!

No.

The same Video signal is sent to all Outputs at the same time. The PIP buttons on the remote are for your TV/Monitor PIP (if you have that option).

Does this apply to audio signals as well. I would like to run a digital feed to my receiver for 5:1 surround, and analog to my plasma so that my wife/daughter can use the TV speakers.

Yes it does apply to audio signals as well. What you want to do will work just fine. And might I add that it's very kind of you to simplify things for your non-techie family members. :)

Thanks for the info.

I just got a Phase III box, so here is my experience.

First I am using Buckeye Cable in Toledo, a small, private, cable company. They use the iGuide.

My firmware is 12.18.

I am using a HDMI to DVI converter, because my TV has DVI.

I have NO PROBLEMS getting Dolby Digital signals to my Receiver on digital channels. HOWEVER, analog channels are now NOT in DD. this is different than my Phase I box, that i traded in. To repeat, DD works fine on both tuners on digital channels, but analog channels NO LONGER are in DD (stereo or otherwise).

I also noticed a SLIGHT improvement in analog channel picture quality.

My father just got a new HDTV with HDMI input, so as soon as he gets his receiver I will report how that works.

I just read through this entire thread for the 2nd time, and here's a few things I found that still seem unanswered. Maybe now that we know more about the new P3 box there may be some answers:

(1) Does the HDMI port pass 5.1 audio? The only way it seems that someone would know this is if the new P3 Moto has been successfully used with an AVR with HDMI inputs. Mjames mentioned that it didn't work with a JVC RX-D702B or the Denon AVR-3806. He also said he was going to try it with a Yamaha RX-V2600 but hasn't reported on the success/failure of that yet. Have you guys heard of anyone who has done this successfully?

(2) Does anyone know the HDMI version on the P3 Moto (1.0, 1.1, 1.2, etc.) ?

(3) Apparently the audio problem described in this thread will be solved with Firmware version 12.22, but there was one possible solution (other than the firmware fix) that I don't think was ever tried by anyone. The idea was to convert the HDMI output of the P3 Moto to DVI using an HDMI to DVI adapter, and then convert it back to HDMI using a DVI to HDMI adapter. Basically since the DVI section in the signal chain wouldn't pass audio, the P3 Moto might leave the optical and coaxial digital audio outputs alone and they would be fully functional on both tuners as well as pre-recorded material. Has anyone tried this?

To repeat, DD works fine on both tuners on digital channels, but analog channels NO LONGER are in DD (stereo or otherwise).

What about programs you have recorded that have DD5.1 audio - when you play them back are they still DD5.1?
If they are, then it would seem to me that the idea stated in question #3 in my previous post should work. Otherwise, those of you with a DVI input on your TV just convert the HDMI output from the P3 Moto to DVI and you'll be good to go! That is, of course, if trabbic reports back that DD5.1 is working on pre-recorded programs too.

At present I still have a hlp6163 and am using its DVI input to connect to the HDMI output of the 6412 III (with an HDMI-DVI hybrid cable). I don't seem to have any of these audio problems (or else have been too dense to notice them). I definitely get DD5.1 on the hdtv broadcasts that have it.

the "Official" fix for this 5:1 DD sound problem is firmware 12.22 so everybody including myself stop trying to boot/reboot/adjust/hookup....etc etc
i'm back to component until i get a firmware update!!!
For the past couple weeks I've been joining in the P3 Moto discussion as sort of an "outsider" because I thought I was using the P2 box. Anyways, about a week ago my P2 Moto 6412 completely fried and Adelphia had to come replace it. When the cable guy arrived with the new box, I asked him if they had the new Moto 6412's yet, and he said "no, we'll have these ones for awhile until Motorola can work some bugs out." He then unplugged my broken 6412 and installed the new one, which worked great. Based on what he said, combined with the fact that my TV doesn't have a digital video input (DVI or HDMI), I didn't bother to check the back of the new 6412. Yesterday, however, I was curious what firmware I had so I went into the menu and checked it. To my complete surprise it read 12.22! So it turns out that not only do I have the new P3 Moto, but I also have firmware version 12.22 which is supposed to fix the audio issues described throughout this thread. The really sucky part is that I have absolutely no way to test it because my new Panny plasma with an HDMI input won't be here until later this month. Do you guys know of any other way I could test it? The only thing I could think of is going and buying a TV with an HDMI input from BB or CC just to test it, and then return the TV. If I did this, I would want to be 100% sure I could return it and also I wouldn't want to haul a monster TV back and forth so I would want the smallest, lightest TV available with and HDMI input. Any thoughts or suggestions on that idea? Has it been absolutely confirmed yet that 12.22 solves the audio problem? I feel like a complete idiot considering I had the P3 and didn't realize it, but I guess we all have the right to be complete idiots sometimes!

Millerwill, the audio problem is not that you don't get DD5.1 at all. The problem is that you only get DD5.1 on one of the tuners, not both, and that you don't get DD5.1 when you play back recorded programs either. Try watching a program that has DD5.1 on one tuner and verify that DD5.1 is working. Then switch to the other tuner (go to the same channel obviously) and see if it's still working. Then record some of that same program and then play it back (accessing it through MYDVR) and see if DD5.1 is still working. If it works on all of these, then you don't have the audio problem. What firmware version do you have?

OK, Bad news... NO DD 5.1 on recorded shows. My AVR reverts to Stereo (Which I assume means it is receiving PCM) If I watch the show live it is in DD 5.1 but if I watch the show recorded no luck.

I am watching the office right now, and hope to catch up live to see if that will switch it over to 5.1.

To repeat, I get 5.1 on both tuners when watching live, but not on recorded shows.

To repeat, I get 5.1 on both tuners when watching live, but not on recorded shows.
I think you're actually the first person that has DD5.1 on both tuners but not on recorded shows. This whole thing is very strange to me. It seems that if you go from HDMI to HDMI you get DD5.1 audio on only one of the tuners and not on recorded shows. If you go from HDMI to DVI you get DD5.1 audio on both tuners but still not on recorded shows. That doesn't make sense at all!

Well, I can confirm trabbic's results above: on my hlp6163 (yes, my 73" Mits has still not arrived!), connected HDMI from the 6412III to DVI on the Sammy, I get DD 5.1 on both tuners--I switch back and forth between them--but when I recorded a segment and played it back, it was not DD 5.1 ( but DDPLIIx).

Do you have firmware 12.18 too?

Update:

I can no longer get DD on both tuners. :confused: Now it will only work on one tuner...

This is so wierd... It seemed that this started after I recorded some shows tonight.

BUT, if I power down the cable box then I can get DD on both tuners... (by pressing the power button)

I'm starting to not like the hdmi input afterall, with my panny pm50u plasma connected to hdmi i get some serious overscan issues, i see about 1" more screen then with component, which is ok for HD broadcasts but when they switch back to side bar SD on commercials i will sometimes get a white bar on top of my screen pulsating, very annoying!
I had another panny plasma a PA25 which i had them connected side by side before i returned it,and i could see peoples faces on a boxing match that i couldnt see on component out on the pa, also i had my htpc hooked up to the pm50 and have the same overscan problem.
What i understand consumer plasma's have no overscan adjustment, i cant find any in the service menu.
I might just reserve the hdmi for a upconvert dvd player for now, it will be awhile before COX updates there firmware anyway as they told me there just in the beta test stage.
Adelphia really seems to have there act togehter considering 5 yrs ago they really sucked and were on the edge of brankruptcy.

Well unfortunately it sounds like the audio problem exists on both HDMI to HDMI connections AND on HDMI to DVI connections as well. I'll see if I can go pick up a TV with an HDMI input to confirm whether firmware 12.22 actually solves it or not. Which store is more "easy going" with returns, Best Buy or Circuit City?

I agree. I was completely amazed when I saw that I already have the 12.22 firmware update!

Do you have firmware 12.18 too?

Yes. And we are all waiting anxiously to see if your '12.22' does the job!

Yes. And we are all waiting anxiously to see if your '12.22' does the job!
IT WORKS! IT WORKS! IT WORKS! 12.22 fixes the audio bug! :D I just went to Best Buy and bought the cheapest, lightest TV with an HDMI input they had, a 23" Samsung LNR238W LCD. I also got the cheapest HDMI cable they had, which was a 6' one made by AR (still cost me $60!). I ran the HDMI output from the P3 6412 to the Samsung LCD, and the optical digital audio output to my Denon AVR-2805. The exciting news is that DD5.1 works on BOTH tuners AND on pre-recorded shows as well. So those of you with audio problems (most likely with firmware 12.18), rest assured that 12.22 does indeed fix them! Before I pack up the TV to return to Best Buy, is there anything else you guys want me to test?

Sounds great, myapplebuddy; you deserve the AVS Service Medal! (You can put this on your CV!) Now if COMCAST will just get off their rear and send out the 12.22 to all of us.

We knew this 2 weeks ago it would work, your nuts going out buying a lcd to test that out....all you had to do was READ the PVR forum, adelphia had the firmware for awhile!!!
I'm back to component and i dont see any difference over hdmi.....NONE!!

Thanks for going above and beyond!!! Now only if my cable company would believe me...

One question, do you get Dolby Digital on Analog channels? That will be a quick way to see if the firmware update has fixed the problem.

Oh, I almost forgot, does Adelphia use iGuide where you are at?

Im have to say that Comcast has done an excellent job in training its Customer Service reps. These people are a wall between the Customer and Service. They will not do anything that isnt in their script.

After at least 5 phone calls regarding the audio bugs and FW 12.18, I was unable to even get someone who knew what firmware was. I kept asking to speak to someone who would know about FW and was told there is nobody you can speak to. I asked for another phone number and they told me they didnt know of any other phone numbers to call. I asked for the corporate office number and they told me they didnt have it.

They directed me to the website which I had already tried. I received an automated response to my question suggesting that I make sure my cable connections were tight. Thanks for that bit of information Comast.

You would think that there would be a technical support phone number to call with issues like this. All the Comcast Customer Service people want to do is send out a technician. I told them I dont need a technician and all I need to know is what the status of 12.22 is.

I guess all I can do is wait for 12.22 to be released which could be days, weeks, months or a year from now. You would think that spending $100 a month for a service would afford you some Customer Service.

Even getting a technician who knows what they are doing is doubtful. Here is what happened at my second try at a Comcast HD cable box install after I asked for a tech who knew what he was doing because the first one had no clue.

Me: Here is the digital audio coax. Please connect it to the SPDIF output.

Cable guy: Whats that? He then proceeds to plug it into the left audio jack.

Me: No plug it into this one that says SPDIF

Cable guy: I never saw anyone connect there before!

Me: rolls eyes and does not say anything.

When you call Comcast, select Support from the menu, not billing, or service, then ask the support CSR for Tier 2 tech support!

also, the Firmware has to be configured for each cable feed's Head End Configuration. Some people will never get 12.22. The firmware is not the same for everyone. Thats why you have some areas that have 9.15, 9.17, 9.19, 9.21, 10.12, 11.08, 12.12, 12.14, 12.16, 12.18, 12.20, 12.22, 12.24 ect....

when Moto releases the newest firmware, then the cable operator has to modify it to work on there system, then the local feed head end also has to modify it further ect.....

on my 6412p2 I have F/W 09.21 beta

If your local head end is unaware of the problems in your area, then the firmware will never be patched and released to fix those problems.

Your basic CSR is a $8 - $10 per Hour paid Phone Sec, that has very, and I stress VERY Basic info. Always go / ask for a Level 2 Tier Support Tech for problems.

Good Luck!

We knew this 2 weeks ago it would work, your nuts going out buying a lcd to test that out....all you had to do was READ the PVR forum, adelphia had the firmware for awhile!!!
I'm back to component and i dont see any difference over hdmi.....NONE!!
I've been nuts for awhile...ever since AV became my hobby! :D The reason I went and bought an LCD to test this out was because I hadn't read anything "definitive" that 12.22 solved the audio problem. And by the way I read through this entire thread twice and I was well aware of your posts regarding 12.22. You simply reported that someone else in the "PVR forum" reported that 12.22 solved it, but I couldn't find any posts where someone had actually said, "I tested it, and it worked!" It seemed like everyone was saying things like, "12.22 supposedly solves it" or "it was reported in another forum that 12.22 solves it." Basically I wanted a definitive answer and now I've got one! Besides, it's not really that big of a deal. My entire time commitment in this firmware 12.22 test will end up being about 2 hours (purchasing, set up, pack up, returning) because BB is right down the street from me. I probably would have spent more time searching these forums for a definitive answer than simply going to test it for myself!

I'm in your camp, myapplebuddy: one hears so many rumors and second-hand reports on these forums (which I'm not complaining about--we all want to hear the latest) that the only way to nail these issues down is a definite EXPERIMENT. And I for one, appreciate your making the effort to do it and report your results.

I have a question on this, is the HDMI output clearly nicer than the Component, or can you tell that much of a difference?

Also, any word if any Comcast dealers are getting this?
It looks worse than component. Also no sound comes through the HDMI pipe just video. Also, when changing channels, it takes longer to make the switch over HDMI than Component. The other problem is that the analog stuff looks horrible stretched and the box won't allow you to change the aspect ratio.
IMO, I don't think HDMI is ready for prime time with cable tv.

I have 6412 Phase III connected to my Panny Plasma via HDMI and the quality is noticably better then the component connection. It is also a 1 cable connection, versus 5 cables for component.

I think HDMI is ready for prime time, at least in my situation.

Mine looks equal to or slightly better than component. The sound plays just fine (I only use the TV speakers on this one). Changing channels is no different. The analog stuff is not stretched unless I tell my TV to do it. 1 cable instead of 5.

When viewing any material with my DCT6412 III, the audio is delayed ~1/4 second behind the video. This happens on both the coaxial and optical outputs.

I have the digital audio output going to my Harmon Kardon AVR-135. I have the STB connected to my Philips 42" display via HDMI. I discovered this when I decided to turn up the volume of my display, and noticed an echo effect. The audio of both the receiver and display speakers were not synced. I qualitatively determined that the receiver audio was behind about a 1/4 second.

I have tried changing the delay settings on my receiver, but that did not change anything (and it shouldn't). I have also run the digital audio from the display's digital output via coaxial, but that seems to only pass through PCM, not DD5.1 (not sure if it is a limitation of the display or the fact that the STB is only sending PCM over HDMI to begin with). Running it this way the audio was synced perfectly, but as I mentioned before, no DD5.1 is passed. I also used a different DD5.1 receiver (Kenwood VR407) with the same results. This would indicate the problem lies with the STB.

Is there a known problem with these STBs and delayed audio with the digital outputs? Or is it just me? I would welcome any users that are able to test it out using the HDMI video/audio and comparing it with the digital audio output of the STB. Thanks.

I'm adding a .117 second audio delay to the digital optical connection to my receiver to sync the audio with my Samsung HLR5668W 1080p HDTV over component video. Comcast San Francisco bay area.

Where do you see secondary audio under menu?
I don't see any secondary audio on my meny either. This is the menu when you are powered off, right? All I see is the tv screen setting (ie, 4:3 or 16:9), the default for4:3 input and a bunch of closed captioning options.

Hi all:

I followed Keenan's steps to reprogram right and up arrows to 30/60 second skip functions... That part works but now the right/up arrows have forgotten their basic function which is to move the channel up and time to the right in the Guide mode! :(

I know I know - I am an idiot. But, could someone help this idiot undo my most recent changes so I can start over?

thanks!

When viewing any material with my DCT6412 III, the audio is delayed ~1/4 second behind the video. This happens on both the coaxial and optical outputs.
I have the same problem on my P3. I am running component cables for video and using the digital optical audio out. It seems like the audio is synced fine for some channels but is way off on others. I think your estimate of ~1/4 second is similar to what I'm experiencing. The problem is there is no way to fix it that I know of. My Denon AVR-2805 has an audio sync function, which delays the audio up to 200ms. The problem is that the audio is already coming LATER than the video, with the audio delay set to 0ms. Is there any device that will delay a video signal in ms increments? I'm getting my P3 replaced on Monday by Adelphia with a new one because I'm convinced mine is possessed by something. It's not just the audio problem. It's also extremely screwed up when it comes to being responsive to RC commands. I know that it's common with all 6412's to have sluggish RC response sometimes, but this is way, way beyond sluggish. It's sluggish to the point of making my wife and I want to throw things at it. Television is meant to entertain, not infuritate! Anyways, I'll report back if the new box is any better with the audio sync.

I just got this box and I have run into trouble w/ the DVR. If I have a show I recorded, and play it, it works, but when I try to fastforward or rewind it goes superslow, no matter what "speed" I set the fastforward/rewind to.

Anyone else have this issue, or have any idea how to resolve it?

Thanks

I've noticed the new Series III box having a louder HDD than the Series II. Is this just me? Or do I have a bad box (the installer did drop it, it was laying on its side then it fell flat).

Take the box back to your local cable office & ask for a brand new still in the wrap & box 6412p3 duel tuner DVR. Be sure to tell the office Mgr. about the service installer dropping the STB durring the install.

They should know better then to sit it on it's side standing up.....

I wanted to go to the local office to begin with. One person on the phone said you can swap DVRs at the local office, another one said they dont have DVRs there.

At least for Comcast, MOST local numbers now send you to the national 1-800-comcast system and is answered god only knows where!

Always ask the CSR where they are located, when asking area / local specific questions.

buy yes, you can go to your local office to replace, return, get equipment.

When the TV is ON and the DVR is ON!! hit the menu button a screen will pop up scroll down to "SAP" secondary audio, now just hit Down arrow then B the UP arrow then B again, another screen will come up!!!
It shows you the firmware and room left on the hard drives....etc....i will post screen shots for you newb's!!.......sheesh!!

Click on Menu and you get this screen.

You'll see i have firmware 12.15...ARGGHHHH and 52 gigs left on my dvr recording....etc

You have a completely different GUI than my P3 6412 has. I would suspect this the case with those who are confused by the whole "secondary audio" topic. Where do you live? Maybe your cable company uses different software for the 6412.

Bud-man, first, I am not a newb, I've been playing around with this stuff for many years. Second, your firmware looks to be different than what many (or most) of us have. I am on 12.18 on my Phase III. I did a couple of screen shots myself. Not the best shot, but you'll get the gist.

TV ON and DVR ON, press Menu becomes Menu 001

And then TV ON and DVR OFF, press Menu becomes Menu 002

Bud-man:

You must not be on Comcast/iGuide. I'm with apple and Bobby. I have no idea what you are looking at. I get the menu like Bobby.

Don't always assume people don't know what they're doing. Think about possible reasons why people couldn't follow your instructions. Different provider/system/location perhaps?

Sheesh! Argghhhhhh!

I'm on Cox....you guys are not using pioneer passport with your 6412's as you see i have passport echo software.....12.15 is my firmware...they are real slow to update.
The girl receptionist at Cox said she had the new "beta" firmware in her's, might be months before i see it!
Ohh well i really cant see any diffence in quality over hdmi/component anyway.....very small if any inprovement, text maybe a lil sharper thats it.
In the first picture if i hit A i get the advanced menu with picture settings and audio, parental control etc......
Bobby that first pic of your settings looks pretty lame, i like my interface alot better, your second pic is what i see if i turn off my dvr then hit menu, i dont use that to set my picture, theres more detailed in my advanced menu like 1080i/preserve 480p picture ....etc

Just got off the phone with Comcast in Baltimore. They've received 12.22 but haven't started updating customers with it yet. No ETA.

Unpredictable DD5.1 here until then...and perhaps after.

I wish they allow change of aspect ratio and CC without having to turn off the DVR. Looks to me the Passport software can do just that. Of course all other HD boxes I used before could change AR and CC without DVR off first. What a moron who designed this feature in the IGuide software.

What's the CC you're referring to? Cable Card?

What's the issue?

The STB built in Analog & Digital Closed Caption System. (CC)

You have to turn the STB off and access the user Video menu to turn on or Off & Make changes to the CC decode system of the 6412 STB.


Best thing to do is to use the CC system of your Display / TV / Monitor Device.

Just hook up the Analog RCA Video Cable from the STB to the TV to access the TV device CC system, works on mine.

Are you saying that I can be watching the dvr over the hdmi input, but will still get CC as controlled by the tv if I just have a composite video connected? Wouldn't I have to be viewing the composite input?

I have the same problem shepleffel. All you can do is reboot the box by holding down the power botton. Any other fixes, anyone?

Are you saying that I can be watching the dvr over the hdmi input, but will still get CC as controlled by the tv if I just have a composite video connected? Wouldn't I have to be viewing the composite input?

Sorry, no you would have to use the Analog Composite or S-video input for viewing of the CC. via the Monitor / TV device CC decoder. :(

Let's hope the DCT-7xx series does not have the same problem and will allow the STB CC / DCC to be turned on/off via the remote with the STB still on! Like the way CC works on a DVD player.

Is there a general issue of CC over component? I found I can only get CC from my Panasonic dvd-r wirh s-video/composite, but nothing shows with component.

I just hooked up the moto phase3 to my new Mitz DLP (comcast digital platinum w/HD and DVR) thru HDMI (audio going optical to my receiver) FW is 12.18.

Good news is (so far) I have not seen audio lag (I did before I hooked up the STB when I was just going straight thru ant-1) Bad news is this:

I'm getting horrible pixelation (like a loss/slowdown of the digital feed, or if any of you had digital sattelite,like a bad rainstorm..) *ONLY* on the HD channels!! SD, DVD,VHS all look fine. It's like the box/cable cant "keep up" with the increased data stream? I have not called Comcast yet as I am running a splitter (or two) at my house and I want to eliminate that as a possibility first. Could a splitter be causing the issue (at high frequencies?) since all digital SD is fine...

Thoughts?

Could be the splitter although I'm not having that problem with a splitter. I did have that problem when I first hooked my sxrd where I had the cable going into a vcr and dvd-r and the rf out going to the tv. None of the hd channels had good reception; kept breaking up like you said. So could be a similar situation where the output of the splitter isn't passing the hd freq properly?

SD channels are either analog or 64 QAM digital whereas HD channels are 256 QAM digital. The 256 QAM signal requires about 7 dB more in the signal to noise ratio. Do you have other equipment connected to the cable system? This equipment could be generating noise that is degrading the SNR for the HD channels. Another possiblity is grounding. If the cable is not well grounded you could have 60 Hz HUM degrading the QAM signal. QAM signaling carries information in both the amplitude and phase so anything that could degrade either one can be an issue. A bad splitter could be preventing a good ground connection. So try reducing the setup to a minimum of splitters and connections to debug the issue.

If you are worried about signal strength use this procedure:

You can check the actual signal strength (on the digital stations) with the following procedure. Turn the DVR off, then immediately press enter. The diagnostics menu will come up ... go to option 4 (something like D04) and you will be able to see the signal strength for both tuners. Note, tuner two is always less than tuner 1 because it appears that Motorola splits the signal in the DVR again.

Take your splitter out and recheck.

SD channels are either analog or 64 QAM digital whereas HD channels are 256 QAM digital. The 256 QAM signal requires about 7 dB more in the signal to noise ratio.

If your area has ADS, then channels 2-99 are 256 QAM also.

I get pixelization on some of those 2-99 channels some of the time, not all of the time. I am going to try a Electroline splitter/amp at my point of entry. See if that helps.

It's definitely the splitter. I isolated it by removing and running the cable straight to the STB and Wala! Mind you there is another splitter upstream running to another room, that would have been my next step. (requiring a trip to the crawl space under the house, hense my attempt at removing the splitter at the TV first) :p

So it's off to Radio shack for a "quality" splitter (I still would like to use for the ant-1 to the TV for P-in-P in addition to the HDMI from the STB)
