Motorola DCX3400 and Samsung HLT6189s Problem - Page 3

post #61 of 103
This is the kind of stuff that makes me just HATE technology.
I, too, have this problem with my DCX3400, Onkyo 608, and Mitsubishi WD73C9 display. My Onkyo offers HDMI "pass through" and I believe it is only with this enabled (so I don't NEED my AVR on), that this problem persists. My box is alternating flashing DUI (DVI) and the channel EVERY morning when I come downstairs and the format output has switched to 480. Having defaults set to 1080i appears to be just a suggestion that Motorola does NOT respect. It sucks and I don't know what to do. Running HDMI directly to my TV (don't even know if this would fix it) would suck for 2 reasons: 1. I'd now have to futz with the TV inputs when I shouldn't have to. 2. I'll lose my "on-screen" volume and display that my Onkyo interjects into the signal. Boy, I really love this HDMI wonderfullness.

Hello all,

I am the original poster of this issue. After a long battle, I've finally fixed this issue.

Here is the simple fix: I installed the Monoprice HSP-102M HDMI Splitter Amplifier between my Sony Amp and the Samsung TV. The HSP-102M is only $35 from Monoprice.com. I have tested this and the Motorolla box DOES NOT lose the user defined settings!

I hope anyone and everyone with this issue will try this solution! It works for me and I now have all devices using HDMI for video and sound, with no need to run optical cables!

Thanks,
Tom

I too have been battling this problem for quite some time and also never saw it with my previous Motorola cable box. You can easily watch the progression and can see that it is on the second polling that it resets to 720p. I believe they do this, because they want to assume a lower resolution if the connected device is only one that supports the lower res, because if they didn't you would have no video. What bothers me is that it can be clearly observed that this has to be the Motorola box....by reason of dedcution if nothing else. I have seen a myriad of receiver brands, a myriad of TV brands, but one common denominator...the DCX-3400; plus the previous Motorola HDMI STB did not exhibit this issue. Yes, there are a few "workarounds" but that is a band aid approach and doesn't fix the problem. I have a Toshiba TV, with an Onkyo receiver......I have used these workarounds....the bottom line is that I bought all high end equipment, with full HDMI support and my cable box won't allow me to exploit this equipment. I am closely affiliated with the big M, and it dissapoints me that this issue is kind of being shrugged off as everyone else's problem but their own. I would guess that a some kind of firmware update could be written/applied and they could solve the problem, but my guess is that they don't want to expend resources to correct this.

Hey tnbtaylor,

I too have the same problem; I could not narrow it down to the culprit until reading the forums. I was blaming the Denon receiver. Here's what I have:

Comcast DVR DCX3400
Denon AVR3310
Mitsubishi HDTV WD-60C9

I have no problems if I connect directly to from my DCX3400 to the TV. Add the receiver into the mix and the DCX3400 starts resetting to defaults and messing up the picture. Anyway, how does the HSP-102M HDMI Splitter solve this problem?

Great thread!!! Lots of good follow-ups...especially since this started over a year ago. I like that you posted the Motorola responses. You'd think they'd fix it.

hello everyone, i too stumbled upon this thread with the same problem, my dcx3400 is connected thru my Yamaha V663 to a vizio m420vt display. same issues the dcx will not hold its settings,,,,thinking about this handshake would running component cables between the dcx and the receiver solve this and keeping everything else hdmi?

just a thought

Dom

Hey Dom,

Yeah, you are right. Component cable eliminates any of these problems. I ran component from the DVR to the Denon 3310 and then HDMI from the Denon 3310 to the TV.

One problem I do have is that I have Zone 2 speakers. I like to pump sound throughout the house (Zone 2) when I'm watching a football game. There is a sound delay between the main zone (main zone is delayed) and zone 2. I think it's from the video processing or I/P scaler. If I take the video processing off, I cannot see my TV. If I keep it on, I get a delay. If I had pure HDMI, this wouldn't be an issue.

Glad to read I wasn't going crazy! Just bought the Sony HT-SS370 for great price and thought I was going nuts when the cable box starting reverting back to 720p.
When I get home today I'm going to run the cable box direct to my Sony KDL-40XBR6 and optical to the reciever to see if that solution works.
Thanks for everyone's help in trying to solve this issue.
Gotta love Motorola & Comcast!
Jimmy!

Great thread, and I'm glad I stumbled across this.

I too recently just purchased a new receiver (Pioneer VSX-32) because I was tired of all the cables and wanted more HDMI inputs.

I hooked up the DCX3400 box to HDMI 1 on the receiver, and sure enough, every time I switch input sources, FM, Blu Ray, CD, and then back to TV, the DCX3400 resets to 480p and 4:3L mode. I got so tired of having to go into the menu to reset everything I decided just to bypass the receiver for now.

So, now I'm back to more cables, DCX3400 > Sony HDTV, and optical audio out from DCX3400 to A/V receiver.

I also have a Harmony One. I'm wondering if I could write a macro which would change the DCX3400 back to 16:9 and 1080i using the remote. That way I could at least revert back to using the A/V receiver for everything.

I thought HDMI was supposed to make lives easier?

I have the Samsung HL61A750 TV with the DCX3400 box. I use the native mode and the setting will stay until their is a power failure then the Motorola box goes to 720p. Also if I disconnect the HDMI cable and then reconnect the cable the box will switch to 720p. In addition my PS3 when hooked up to the same input using the video auto detect feature in the crossbar menu picks up all the display modes correctly. Therefore I have to assume the Motorola DCX3400 is to blame.

Gotta wonder though. Everyone blaming comcast and motorola. Yet many TVs and receivers work fine with this cable box, all through various cable , telco companies. Many of you had success going straight to tv. I have the same box and use it with a reciever with no issues. Would it not be fair to blame something else?

I mean if a box works fine on one tv but not through a receiver, how is it the box or the cable companies fault? If that same box also works fine through many peoples receivers and various setups how is it motorolas and the cable companies fault?Just because the previous box works fine maybe it is the receiver or tv that is not compliant with the newer box.

Would it not be easier to have a tv or receivers hdmi to be compliant with the few variations of cable boxes versus having the cable boxes be compliant with the thousands of TVs and receivers?Or even better, a standard by which all hdmi devices have to abide by. For example, If i have a box that doesn't work right with my tv then bring it over my friends house and it works fine, how can I come to the conclusion it is the cable box that's at fault?

I'm not trying to defend anyone here, but common logic has to. I'd like some expert evidence and reasons to blame a box and company that works fine for millions of people over the few that have issues running it through THEIR equipment.

Any real explanations as to how this could be motorolas or comcasts problem, aside from that it works one way but not the other, would be appreciated. If it could be proven there is a problem with the box it would be helpful to everyone but placing the blame in the wrong direction gets us nowhere in the long run.

IMHO and I've said this before , but the current HDMI standards are not the best way to go about things and it has been poorly implemented from the start. We've had multiple variations through the years since its inception and this has led to many compatabilty issues and in some cases making some equipment obsolete feature wise. I think if HDMI, and whoever controls it's standards , wants to be the simplest and foremost standard of connection, needs to tighten the reigns on the very equipment that is going to be using it.

Just my two cents. But glad most of you found a way around this madness.

Then why only this box and not the other Motorola series boxes? Also I have a RNG110 and it does not exhibit this problem. (All of these boxes including the DCX3400 were hooked directly up to the same set and only the Motorola DCX3400 had this problem. Also if the EDID information was not proper the PS3 would not correctly dected all the video modes.

The same could be said as to why only the minority of equipment does not work with this box properly , no? Like I said, if a box works properly for millions of customers across multiple companies, how can the box or the cable company be at fault for the hundreds that don't work?

Not to mention that in the case of many who have this issue, the box works fine straight to the tv, but not with an AVR. If the EDID information was not proper with the box , would it not exhibit the same problems in all or most instances?

Believe me I'd like to know some real factual information on why this is possible myself. I'm just looking at it from the other side.

superactionguy i changed to component and optical from the dcx to my yamaha and left everything else hdmi and all is fine now.
post #74 of 103
Do most customers know if their box switches to 720p, I really doubt it. I have to use HDMI since I need 3D.

D'oh! Never thought of that. At that this way I can keep an open HDMI on my TV, and get the benefits of 1080p up-conversion through my receiver, while still being able to use the GUI from the receiver as well.

Thanks!

Most of these update will actually come from Motorola after cable companies find problems so hopefully Motorola will issue the fix for all cable companies.

Another potential fix, if you have a Samsung TV, is to turn off Anynet+ (HDMI-CEC) in the Media Play menu, as that seems to mess up the handshake when the TV is turned back on.
post #80 of 103
Tried turning off AnyNet - it doesn't help. DVR still reverts to 720p at TV turn-on. I've tried various ways in DVR setup, including Native, 1080i, modifying selections in "MyTV supports the following formats" (which are overwritten by HDMI comm), etc. Also turned off HDMI control function in receiver.

Samsung UN46B8000 46 inch TV
Yamaha RXV565 A/V Receiver
Comcast DCX3400 DVR

DVR HDMI --> A/V receiver HDMI --> TV HDMI

So Comcast has admitted this is a DCX3400 problem? Did you got that info from Comcast? Is the fix here yet? If so, do I have to ask for it specifically, or would the fix be pushed to all Comcast customers automatically?

Are they also going to fix the limitation (2 or fewer) on the number of downstream HCDP devices?

They are doing a 30 day test now. If their are no problems it will be a nationwide rollout. I also have the DCX3200 box and it exhibits the same problem. Also with a HDMI receiver it give me a message about HDCP copy protection. This is supposed to be corrected. I also have the Pace RNG110 and for the most part is works without any problems through the HDMI receiver. The only problem I had was using On Demand where I would have a problem viewing HD material where the HDCP would kick in and give me a blank screen. By eliminating 480i and 480p from the viewing resolution options I got rid of the problem.

i tried searching for this peice on Monoprice, I wasn't sure which peice it was exactly to choose.... Could you post a link? Thanks....

Just came back to this thread after researching the issue in the past and just giving up and using component.

Googling "Monoprice HSP-102M" results in a page that says it is now discontinued and replaced with product ID 8204.

Bump.

Not sure what, if anything, they did because my box reverts to 1080i. I have an onkyo receiver and a harmony remote so I am going to try the remote trick posted earlier.
post #87 of 103
I had the same problem with my DCX3400 which recently replaced an older DVR from Cox. If I turn on the tv first, and turn off the tv last, the settings are preserved. However, I use a Harmony one, which I could program with the proper turn on sequence, but couldn't adjust the turn off sequence. So, with harmony one remote, settings were lost with each power cycle.

So, I tried the powered hdmi splitter and it works!!! I can leave the dvr box connected to my Sony ES AVR and the AVR out to TV, all with hdmi, use the harmony one for power on and power off, and video settings are preserved at 1080i! Don't know why it works, but it does.

I am a Happy man!
post #88 of 103
Looks like I'm not the only one judging by this now quite old forum thread.

Just purchased an Onkyo NR609 to replace my aging Onkyo TX-SR674 which was having HDMI switching issues.

I noticed my DCX3400-M reverting to 480P almost immediately, even though I kept changing the settings back. I ended up going HDMI straight to the tv (Sony KDS-50A2000) and going optical from the 3400 to the receiver. So far, so good - no reverting to 480p yet.

I wonder why I didn't see this issue with the 674, but do with the 609.
post #89 of 103
I've been following this thread for quite a while now. I have been using Comcast/Xfinity Motorola boxes with a Denon AVR-891 receiver and Samsung plasma TV. HDMI is a real nuisance. Glad to know that using a powered splitter can work around the issue, but that doesn't really suit my needs. I wish Motorola would fix this already... their design leaves much to be desired.

My cable box has multiple active outputs: HDMI to the receiver (and from there to the TV) and component/TOSLINK outputs to a DVR. Using an RNG110 box simply didn't work: the two sets of outputs conflicted with each other and usually wouldn't work simultaneously. I'm presently using an RNG150N with no problems except for the HDMI switching issue. When I turn the receiver on before the TV, the video setting in the service menu reverts from NATIVE or 1080i to 720p. The same problem usually happens if I simply change the input setting on my receiver to something else (e.g., CD), regardless of whether the TV is on or off.

I just tried a DCX3400. The only difference I've found is that with the box set to 1080i in the service menu, changing the input on the receiver no longer reverts the setting to 720p. This still happens if the box is set to NATIVE, however (or if the TV is powered on after the receiver).

Also, the DCX3400 froze while in the special menu.

I especially dislike the fact that this drop in resolution also affects the component video feed from the cable box! If not for that, I'd be able to avoid this problem most of the time. I'd use the HDMI feed only for 3D content and when I can't pass video through my DVR.

Unfortunately, I'm also having problems reliably recording from Comcast to the DVR. But that's another story.

Some good folks at Comcast are trying to help me get somewhere with these problems. It's slow-going, but I remain hopeful.
post #90 of 103
I have to amend my previous post and declare that, most of the time, the behavior of the DCX3400 really isn't any different from the RNG150N with my equipment. If I have my TV and receiver on, then change the receiver input to CD, then change it back again to cable, the resolution does often drop to 720p. Even if I turn the TV off first, change the receiver input, then turn the TV back on, the same thing happens. These boxes just love 720p.

But that said, I just switched my receiver back to CD and turned off the TV. I watched the DCX3400's front display indicate an HDMI handshake... and to my surprise, the resolution jumped from 720p to 1080i! I never saw it go in that direction before... But then, when I turned my equipment back on in the sequence that usually works, the resolution dropped again.

Testing the RNG150N, I find it behaves similarly. As long as the TV stays on, I can change receiver inputs and it sometimes won't drop the resolution. But as soon as stuff gets shut off, there's often no way to avoid the change. Powering the cable box off and on doesn't seem to help.

I think I'm ready to try the Monoprice HDMI splitter.
