So, with all the DTV people (work there) that read this site why have we heard no definitive answers from them? The only guy I know of that has an in with DTV is Earl. Sure would like to hear from him.


Again, answers and possible causes from us, the customer, yet no response from someone associated directly with "D". And this is certainly not the only lip sync thread here or on the avs forum. Switch back and forth between SD and HD on "Everybody Loves Raymond", on TBS.

Today I did not notice any real problems with audio sync on the TWCHD or CNNHD. I checked both my receivers.

The DR20-700 is using the HDMI output and my HR20-100 is using the RGB output to an SD TV.

Last night I had some terrible Discovery HD issues. Some of the material was recorded from earlier in the week, and some of it was recorded earlier that night. Mythbusters has been out of sync (upwards of 3-5 seconds) on every episode for me for the better part of a month now! Argh!

I get sync issues on both of the HR20's (identical models) when recording the same show... though sometimes one is slightly better-synced than the other.

I have noticed this problem on my system much more frequently on the "new" HD channels (i.e. MPEG 4) vs the older HD channels (MPEG2 locals, etc)... I'm using HDMI to the TV and an optical to the receiver.

My wife is ready to kill me with all the problems this HD stuff has... and quite frankly, I'm ready to pay the cancellation fee and just dump DirecTV at this point.

Anybody else amazed at the shortsightedness of the standard? Why is there not a sync signal in the audio/video? I wouldn't think this would be that big of a problem.

Having been forced to sit on an ANSI Standards committee (I'm not sure what I did wrong to deserve such a punishment), I am not in the least surprised.

Everyone comes to the table with a financial interest in protecting their own methods/products/legacy... and all it takes in a handful of participants to destroy a standard. A lot of the people involved in the committee are either the incompetent, competent specialists in who don't know enough to understand the big picture, or have other more important priorties. Those who really care about making the standard succeed are often punished with high workloads or attacked for promoting ideas that might change the status quo (i.e. cost someone money).

The fact that there's ANY ability for this stuff to work still amazes me...

That said, I'm still unhappy having to pay for a defective product.

I guess I don't blame DirecTV completely.

Lots of users of the TivoHD complain of the exact same problem.

Cable, FIOS, Dish, DirecTV - people are reporting this everywhere.

It's tough to blame them for not following a standard that doesn't exist.
And it's not like they're doing it on purpose.

But still it's annoying as all get out...and they are the ones that are going to have to fix it...

I was watching Mitt Romney's speech this morning - good speech - and the sync was bad on CNN-HD. I switched over to MSNBC. After the speech, I switched back to CNN and saw something I've seen before. The sync was different for the talking head in Texas and the talking head in Georgia. The anchor in Atlanta was closer but still off a bit.

At this point this is getting to be bush league, no pun intended. No matter what errors DirecTV and/or my HR-20 are introducing, the sync is off from the start. Good work, CNN.

I've said it before but this is exactly what we saw back in 2001. It seems we haven't learned much since then. :rolleyes:

I have to say it's clear to me now that D* is actually looking at the problem. They do seem to be adjusting the sync "on the fly" (mostly during commercials). It used to be if a channel went out of sync it would be out of sync for the rest of the evening, and now it is at times fixed (and sadly other times broken) at a commercial break.

This indicates to me they are aware of it and working on it, even if they don't have it right yet.

On break. I thought I'd get something in time for baseball, but...

That is not the problem. Even with a sync signal in the audio/video (as HDMI 1.3 has), it only helps your system preserve the sync, since the audio/video signal is not intact end-to-end, and instead is regenerated from compressed data inside your DVR.

The real problem I presume is the lack of a standard. DirectTV is sending the signals up to the satellite (and back down) in H.264 format w/Dolby Digital audio. The ATSC standard (for example) doesn't cover H.264. So DirecTV had to make their own system, and it doesn't seem they got it right yet.

Somebody certainly is. CNN HD was dead nuts on tonight.

It's interesting that you guys get "Live TV" sync problems. almost all of mine involve shows that have been recorded. Then again when I think about it I don't watch much live TV so that might explain it :)

Try watching "Everybody Loves Raymond" on TBSHD.

I've had HDTV since 2003 and never had any delay until this week.
