May 28, 2007 EDIT:
Basically all the significant sync issues with discs I purchased before the Xbox 360 HD DVD Update came out have been fixed. However there is a new one...
The Matrix is out of sync.
Reports are that it's also out of sync with the Toshibas.
Some from Microsoft had said that The Matrix had been tested, but I guess this was overlooked.
-------
So, my brand new Xbox 360 HD DVD drive setup has audio/video synchronization issues, at least with certain discs and audio tracks.
I only have one TrueHD disc, Batman Begins, and it's with that track that I notice it the most. Actually, unless my eyes and ears deceive me, it seems like the audio lags the video (instead of the other way around, which is what is often reported with other hardware).
Could the Xbox 360 be lagging in audio because of the requirement of decoding TrueHD and then re-encoding it DD5.1 is too much via software? Is decoding TrueHD harder than decoding Dolby Digital Plus? I also wonder if I'm getting slight audio sync issues with other DD+ tracks, but if there it's pretty minor.
I have NO audio sync issues whatsoever with anything else, including 360 gaming, 360 DVD playback, WMV trailers on the 360, two DVD players (including one progressive scan one) with either DD or DTS, or my HD PVR.
My setup:
My Toshiba CW34XC2 34" widescreen CRT and Kenwood VR-510 receiver are hooked up to all my components through a Zektor HDS4.1 component & digital audio switcher. The Zektor is hooked up to the receiver and the Xbox 360 both via optical. ie.
DVD 1 (480p) --> Zektor
DVD 2 (480i) --> Zektor
Xbox (1080i) --> Zektor
PVR (1080i) --> Zektor
Zektor --> TV + receiver
Do you also have sync issues, and if so, with what? I note that others have noticed lip sync problems with TrueHD as well, but with different discs (like Constantine ) and on Toshiba standalones. I don't see many reports of this problem with the Xbox 360 setup, but I wonder if that's just because it's so new.
Is this a hardware issue, an HD DVD disc issue, or both?
EDIT:
The lag IS definitely there with Dolby Digital Plus tracks too. It's very mild, and I suspect most people wouldn't notice it, but it's real. I see/hear it on Batman Begins DD+, King Kong DD+, and Pitch Black DD+ tracks. I have to pay very close attention to see it, but I'm now 100% convinced of it.
Either my receiver/setup is lagging with decoding 640 Kbps DD, or else Microsoft's implementation of audio output synchronization needs some more work.
