DCT6412 III HDMI won't work (sometimes) - Page 8

nVidia cards have been HDCP compliant for a long time. For HTPC, stick with those.

Over the weekend I tested my Pioneer VSX82TsX with a Sony and LG DVD player with HDMI. Both claim HDMI with HDCP compliance. Pioneer seems to pass both Audio and Video just fine. (no audio out of digital out jacks though- as expected)

It's never been the display that is the problem for any of us. It's the Motorola STB not passing HDCP properly through a repeater. KustomMerc and I both have Cox in Orange County, CA using a Denon 4306. DVD players work, computers work, but no Cox DVR.

One of these decades they will finally push a firmware update that will allow us to ditch the component and digital cables and have just one cable going from the DVR to the receiver and then one to the display. We'd like to have a pure digital signal. Can't do that right now.

Great Thread....

Have been searching this for a while.

I too have problems with the 6412 - green screen.

I have not checked my firmware in about 6-8 months - have been using component.

I will be trying HDMI tonight and checking firmware, and also trying changing the color space.

My big problem is my DVD-5900

But I also get green screen with DVD-5900 passing through my AVR-4806.

The DVD-5900 does not have HDMI, so I am using a DVI-HDMI cable.

So my question was could it be the 4806?
Sent it back to Denon - they sent a new one - same problem - green screen

I can understand the problems with the 6412 - lots are having same issue.

But how can a Denon product not work with another Denon product?

I have tried to think of everything - could it be because the 5900 has DVI instead of HDMI - but they are supposed to be backward compatable....

Could it be the TV??

Any ideas??

I will post a follow up when I try the Moto box - it is Cox and area is Rhode Island.

Thanks

Talk to Denon about a firmware update for the DVD player. I remember reading they had some issues with that player....I looked at buying it. Go with the Oppo.

I tried the Moto box - I has stated in my previous post that it was a 6412, it is actually a 6416 III. Checked the firmware - 12.31 Jan 2006 build (Rhode Island) Crazy almost a year old and no updates. I have not called cox on this yet but will be.
I will check the firmware on the Denon 5900, but it should be updated per there web site it looks like there is no updated firmware for it. I had sent it in for the D-Link III upgrade, I assume they would have updated the firmware

I am at the point of trying a cheaper DVD player with HDMI like a Toshiba to see if it works....
Has anybody had any difficulty with DVD players and Denon recievers. I am fed up, I guess I will continue to use component.

Interesting news today (12/7/2006)

I had a couple of techs out here because my 12mbit connection was running at 128k for 2 days and I've been getting audio and video dropout on ALL my 3 HD DVRs. Of course when they get out here, the cable modem is fine. That's fine, so they look at the box and say they need to replace it. Slow down, I've got 3 and I doubt they are all bad. Plus it does it on my TiVo every so often.

While they were talking about swapping a box, they said there were none in the warehouse....because all the boxes are getting a FIRMWARE UPDATE! I about fainted. I'm guessing it's going to happen in the next few days. The tech said he would call me when he knew what day that firmware update was coming. I also have the number for his supervisor, so if I have not heard from him by tomorrow (as promised) I will call and report anything new.

Oh, and the other problem they put in a 2 way amp. Now my cable modem is faster than ever! Hopefully the audio doesn't drop out. It's very evident with 5.1 stuff. Oh, and the wife doesn't like that.

I can't run my HDMI cable from my Comcast Motorola Box DCT-66412 to my Pioneer Elite Receiver VSX82TXS I get and error message which says Comcast does not support HDMI switch. Has anybody got a fix for this problem? HDMI only works when I connect to the TV from the Cable Box. I really want to use the HDMI in my receiver I think that would be the best set up. How do I check for my moto box for it's firmware, what versine is the latest. I went to Comcast's web site and here is what I got:

Some cable TV set-top boxes with HDMI outputs don't deliver a picture
to
displays with HDMI inputs. What is the problem, and is there a
solution?

In some cases, the set top box software does not activate or support
the
HDMI port. In other cases, cable TV set-top boxes don't work correctly
when
used in conjunction with an A/V receiver (but will typically function
correctly when connected directly to a TV or monitor). Investigation of
some
of these devices reveals that this is caused by an error in the way
these
set top box devices implement HDCP. Specifically, some of those boxes
do not
support "HDCP repeaters" (devices that pass along the signal to another
device) such as an A/V Receiver or switch. We believe that this may be
a
problem in the initial versions of these products, and in some cases
there
is new firmware available that fixes this issue in HDMI (newer versions
may
already have this fix). We have been actively working with
manufacturers to
resolve these problems. We suggest that users contact their cable
operator
and request the new software to address these issues.

My set up is the following
Bedroom sounds!
Pioneer Elite Receiver VSX82TXS
Pioneer Elite DVD DV-46AV
Sony Bravia 40XBR1
Motorola DCT-6412 Digital Cable Box With DVR
Polk RTi 8's front
Polk T20e rear
Polk RM 202 center
Polk PSW 10 sub

Welcome to the forum. Question -- Did you any of this thread before posting? Since this thread is pretty much exclusively devoted to the topic of DCT6412's HDMI not working correctly when connected to a receiver -- ALL of your questions are answered multiple times in previous posts.

I'm reading the thread now! Hope there is a simple answer to fix the problem.

Since you are a new ownerof a Pio 82 I isuggest you check PQ on your TV when running video (component or HDMI) thru the receiver. I just tested with 2 Pio 82's and had a really bad experiance . With lines and color bands when running thru the receiver which were not there if you connect the the cable box to the TV direct.

Pio is a great receiver for Sound and has great calibration routine and 3 HDMI on paper but PQ on upconversion is bad. DVD's are the worst.

BTW does your comcast box have direct HDMI out or is it an older one with DVI ? My Denon 2807 passes both sound and video sent from the DCT via HDMI . The previous comcast box I had was one with DVI that did not work. Before anybody asks the firmware verion is 16.20 (same as on the box I had before)

Happy camper for now!

Hi,

I have a Motorola DCT6412/2005 from Comcast. It has a DVI output on the rear, and my HDTV has a HDMI connector.

Can I succesfully convert from DVI to HDMI? Can I get a later box from Comcast?
Apparently from what I have read here the newer III version has HDMI ??

From what I am hearing, HDMI will improve my picture quality over component.

What is the best way to resolve this?

Thanks,

You can convert DVI to HDMI. A little searching will yield about 47 million results and 46 million on this site alone.

As far is getting a newer box...I know you're new, but c'mon....do you think we work for Comcast? Call them. Nothing like going to the horse's mouth.

Actually it is harold280z who has the Pio 82. I have a 72 and I'm very happy with the PQ passed through via HDMI from my Oppo 970 upconverted to 1080i and component transcoded (not upconverted) to HDMI.

I agree the Pio receivers are great for sound. I think my 72 is fantastic. Since the 72 doesn't upconvert (just "transcodes" from analog to digital HDMI wiht no change in resolution) I can't comment on the 82's upconversion PQ. But the 72's PQ for both straight digital feeds, and it's transcoding of component to HDMI are both outstanding IMO.

I have seen some other comments about the 82/84's upconversion not being the best. It uses a Faroujda chip, which is supposed to be the best, but others with "hands on" experience with the 82/84 would have to comment further.

My Comcast box is a PIII with HDMI out, but with FW V12.31 it can not handshake correctly for HDCP any HDMI repeater such as my Pio 72 AVR. I'm still waiting for V12.35 or V16.20 to fix that problem.

I have a DCT6412 III (ver. 16.20) HDMI through a Pioneer Elite receiver. When I came back from a two week business trip, I now have a problem switching my MD6580 DLP to HDM2 and then back to HDM1, I get no signal (snow) on HDMI1. HDMI1 is the 6412, my other equipment is on HDMI2. This occurs if the receiver is on or off.

This worked just fine before I left. I use a Harmony remote and had it all setup... now when I switch to my Roku (HDMI2) and switch back, I just get static on HDMI1 and have to turn the cable box off then back on to reset.

New bug or is what other's are seeing here?

Thanks b.

well the 4th has come and gone....no firmware upgrade from COX. that about does it for me Cox can play these upgrade games till the cows comes home. obviously they don't give a #^%^&^% about all the people that want HDMI switching. I can not help if the rights management has turned this into a bowl of glue. but after spending $2000 for a Denon (#4806) it makes me sorry I ever heard the word cablebox.............

That is very disappointing. Any info from your contact at Cox?

I find it interesting that the techs that were at my house last week told me that all the boxes were being held from deployment because they were upgrading firmware. I should try and find his number and find out if he knows anything.
post #228 of 340
I just got home and hit DVR LIST and this "Quick Tips" thing came up....WTF I thought? They did the upgrade....I check....I'm at 12.35 in Cox Orange County!

I'll hook up the HDMI this weekend on the other box, but I'm guessing I have HDMI switching!

Couldn't wait and didn't feel like going to work today. So I put in the HDMI cable and changed my Denon 4306 to HDMI input for the audio and video. Everything works! I turned it off, back on and everything works!

It finally happened. I feel a tear coming on. So to KustomMerc and everyone else out here in Cox-ville.....you can hook it up the way it's supposed to be!

Oh, and I swear the menus are faster with 12.35. They're cleaner if nothing else. Shows in your DVR LIST show up in BOLD if you have not watched them, and PLAIN if you have started watching them. Nice little feature....

Thanks, that worked for me, now comcast will not have to give me a box.

****************** Happy Holidays************************

just read the the new listings and checked.........yes! I'm upgraded to 12.35

I will get in and change all the components to HDMI and let you know..... Thank you Cox.

no longer waitning in Irvine, Cox country.....Ca.

whew!

I saw the quicktips this morning too.
Guess they flashed last night or the night before.

Now I get to play with the cables again.
I was getting used to limping along without the HDMI
switching too.
post #234 of 340
I got this firmware update about a week ago (maybe more) but didn't even realize it. I noticed the bolded titles in the DVR list view and figured I should check the firmware and never did

HDMI now works great with my Onkyo 674 and Pioneer 5070.

SHould I be seeing any difference in picture quality when hooking the cable box directly to the tv with hdmi vs. going through the receiver? I think I see a difference in picture quality but maybe its just in my head.

You shouldn't in theory. It's just a digital signal, so if your receiver is anything like mine, it just passes a digital signal. I have a setting on my Denon that passes everything as THROUGH and it doesn't change the video at all.
post #236 of 340
well after all that The Denon 4306 with HDMI switching worked with the new Cox firmware upgrade to 12.35 in the Moto 6416. the picture was great. everything worked except the volume problem. It increased when it went from TV to commercial or we found differences in the channels with increased volume. after looking closely it looks as if it's being broadcast that way and the Denon just enhances it. Soooooooo the Denon went on sale this morning on E-bay for $400 less then I paid for it. the Moto box is just to finicky for a Beautiful piece of equipment , Denon AVR 4306.......but let me tell you that firmware upgrade was worth waiting for and I know a lot of you can use it.

Happy Holidays
