DVD Audio out of sync...

[Poyaan]

I have a dvd which i want to add a new subtitle too using TheMatrixx guide, it works fine, but now when i tried it on this new dvd movie it didn't really work.. here is my problem:

When i ripped the video and audio using dvd decrypter i get 2 files:

VTS_03_1 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V
VTS_03_1 - 0x80 - Audio - AC3 - 6ch - 48kHz - DRC - English - DELAY 0ms.AC3

Now i use to check so sound and video syncs with Media Player Classic, but it doesn't, and it should be no delay (see ac3 file 0ms delay), but it's like 2 seconds or something, it seems like it changes during the movie sometimes...

I've tried alot of programs, and i always end up with the same result.

Also if i add the *.m2v file and the *.ac3 file in DVD-Lab it says the video is 02:38:02 and the audio 01:38:04

But the video is only 1h 38min, that's abit strange too...

Im out of ideas, maybe someone else can help me?

Guessing, might try DGPulldown or restream to reset video time stamps.

If DVD LAb is giving a wrong value for the length &/or start time of an m2v, opening the m2v in DGPulldown or restream will give you the option to reset timestamps or set timestamps to start at zero -- I think pulldown works a bit better. This will copy your m2v file to a new file with the timestamps corrected in the m2v headers. I don't know if that has any relation to your sync problems though -- just that it can make some stuff in DVD Lab harder if set wrong -- but as it takes just a few minutes, might be worth a try.

Another thing you might try is running the video through DGIndex. It can make some corrections, and save a new video file. Might also try forceing film in DGIndex & resetting fps in DGPulldown if that doesn't work.

If it helps, the mpg2 file (if demuxed then m2v) has a series of flags in the header (non-video) parts of the file that tell the player/decoder how long it is and so on. Seems these are messed up given the results in DVD Lab. Don't know if it's your only problem, but if a player (or decoding software) plays the video at the wrong pace because of bad data, imagine it could cause sync problems.
