I have had mixed results with THD lip-synch. I don't own many HDVDs (and I haven't tried King Kong yet) so the only title I experienced this with is Batman Begins.

I switched to THD just after the movie started, and didn't notice any problem with lip-synch. At one point I stopped the movie and when it resumed there was very noticeable audio lag. I then skipped back to the start of the chapter, and the audio synched up again.

I was playing the movie on a Sony KDS-R60XBR1, which has some audio lag which I compensate for by putting a 30ms delay on my Yamaha RX-V995.

I won't vote in the poll until I've watched some more HDVDs.

Yes, I've experienced this too, for example with Mission Impossible: III. However, it seems for me that this is actually the lesser problem in a way. Sometimes the sound goes way off sync, but when it is not way off sync, it still may be very slightly but persistently off sync, depending on the title. (This is not true for all titles. For exxample, Casablanca is perfectly synced, but it's just a mono title.) However, for the latter slight sync problem, the problem is small enough that some people may not notice it, especially on some home theatre setups (where there might be slight video lag inherent to the TV).

That is video lag. The compensation by your Yamaha is to ADD a delay in the audio to compensate.

The problem with the Xbox 360 HD DVD setup is that we start off with audio lag. Adding delay with your Yamaha would just make things worse. Unfortunately, there is no easy way to add compensatory video delay for movies.

So, as of today, there exactly 200 voters:

52 people (26%) report audio lag issues (18 TrueHD, 8 DD+, 26 both)
10 people (5%) report "other"
138 people (69%) report no audio lag issues

The latest: We have said that the update will come in "early to mid-spring" and we are tracking to that.

The wait continues... Perhaps by mid to late May...

Did he say what year? That update has been ready for quite awhile now but has not been pushed out yet. *sigh*

He hints it's supposed to come out before The Matrix, which comes out May. 22.

I just my copy of Fearless today. This disc is especially good for testing, since it's a combo.

The DVD side played through the Xbox 360 is perfectly sync'd. The HD DVD side is not.

One example starts at about 1 minute 34 seconds into the HD DVD. (It's around 1'45" on the DVD.) The drumming is out of sync by a split second on the HD DVD. It's just like the Batman Begins hammer scene.

We'll see if this get fixed with the (late?) May HD DVD update, but somehow I'm not optimistic this slight sync issue with these discs is gonna get fixed. I betcha they'll fix the big sync issues where discs go wacky and completely out of sync, but this slight but constant sync issue seems to be a different kettle of fish.

That's as insightful as saying its not raining in 69% of the US, because we don't know what day (what DVDs they've watched) or where they are located (what audio playback [analog/digital] they're using)!

The point was that at least 1/4 of voters did have a sync problem. That's pretty significant for the Xbox 360 HD DVD.

With (SD) DVD players today (and properly encoded discs), I suspect the number would be < 1/100.

we found a pretty systemic issue that caused everything to go off by a little bit. some tracks, like batman's truehd, were encoded slightly off to begin with (i.e. they weren't in sync with the DD+ track), and that, coupled with the delay we added, pushed it into the realm of noticeability for some discs.

btw, to the earlier poster: i just watched total recall recently on the new player code and didn't see any lip sync issues, so it'll be fixed when we ship real soon.

This is encouraging in that it suggests that the more subtle DD+ sync issues I've complained about may in fact be corrected.

Has this "added delay" ever been mentioned before?

I don't know if they did it on purpose. In fact I'm not sure if he's talking about the same "systemic" problem.

right, the delay we inadvertently added is the systemic a/v sync issue i spoke of.

all a/v sync issues i know of have been fixed, or more accurately, fixed enough into the realm of unnoticeability (by our measurements, it turns out the toshiba player also was a bit late with audio, but no one ever noticed. we're now more accurate than the toshibas, AFAWCT).

batman begins problem - this is just how this particular trueHD track was mastered (it was barely off)

For the record, I did have sync issues with my Toshiba HD-A1 as well. ie. At least some of us noticed.

Video of 360 HD DVD audio lag issue - 3 scenes from 2 HD DVDs demonstrating the problem.

(Quicktime H.264 800 Kbps, 30 sec, 3 MB - Sorry for the poor quality.)

These are with Dolby Digital Plus tracks. This should be corrected next week, if all goes well.

Thanks Microsoft!

The Dolby Digital audio dynamics is fixed with the HD DVD Update today.



The audio sync is ALMOST fixed. It's way, way better than before, but not 100% perfect sync. However, it's close enough for the time being, and I betcha most people would not notice it, esp. if they have any lag at all in their TVs.

To test this, check out the Fearless HD DVD combo disc: HD DVD side vs. the DVD side. On the HD DVD side there is drumming at 1 min 31 s. Before, this was way out of sync. Now it's almost perfectly sync'd, but not as perfect as the DVD side.

This could be an authoring issue. I wonder.

Hellfire360 claims that the audio now actually precedes the video by 8-16 ms (although I'm not sure with which titles).

At least AVRs can compensate for early, unlike lag.

The audio on the 360 with The Matrix is also out of sync.

This is after the HD DVD update. Microsoft said they had tested The Matrix, but I guess this was overlooked.

I dunno if it's a disc issue or a player issue, but apparently it's also a problem with Toshiba standalones.

The entire movie is out of sync, but it's very, very mild. If the TV has any lag at all then it won't be noticed.

It's hard to see in many of the scenes because a lot of them don't focus in on the actors' lips during dialogue. However, in those that do it's noticeable enough on some systems (including mine, which is a CRT HDTV and 360) it's enough to be distracting. The lips move a split second before the audio.

One example is at 10:50 when Trinity says "They're watching you Neo".

This thread seems to have been dead for a while now, but I thought I would see if anyone has experience with what I am seeing. I have the 360 plugged into my computer's Creative Audigy2 soundcard over optical S/PDIF. When playing HD-DVDs, there is a very noticable audio delay (maybe 1/8-1/4 s) on Dolby Digital 5.1 output. If I switch the output mode to Dolby Stereo, the is no delay, and there is no issue with the RCA audio cables either, but of course this defeats the point of having a 5.1 surround setup. I have the component cable plugged directly into a projector for video output.

I would like to be able to test this with a real receiver, but since I am a college student, my budget kind of restricts that... Does anyone else have experience with a similar setup and getting it working, or am I out of luck? Also, one weird thing I have found is that switching the output to DTS and back to DD 5.1 makes there be a huge delay (as in 2-3s). While I suspect the computer to be the problem in general, the xbox is definitely doing something there.

So far I have tested: Serenity, King Kong

I was browsing around trying to see if I was the only one with sync issues with the toshiba add on for the Xbox360. I thought I would be relieved to find out I wasn't alone but in actuality it just makes me that much more frustrated I have tested Miami Vice, Knocked Up and 300 ALL with the same issues of lag in the audio/video. My Sanyo 30in CRT didn't seem to have the problem that I noticed however when I switched to a Samsung 1080p LN-T4071 it made me want to throw the darn thing out the window it was so horrible. I have the most current update and have the audio settings on the dolby 5.1 connected through the optical port on the 360 to the TV itself. I have tried without the optical and still have the same issue if not worse than with the optical.

Battlestar Galactica Season 1 Disk 2 - second half of the mini-series.

Severe lip sync problem for over a minute, best seen/heard at the 55 minute and 37 second mark.

Tested with the Toshiba HD-A2 and the 360.
