Audio Out of Sync

[Sakuya]

Hi. I need some help with this file I have. First of all, it is an MKV file. I used VdubMod to extract the video and audio (VBR MP3). I opened the MP3 in Audacity and saved as a WAV. Then I merged the AVI and the WAV together once more. It plays fine in WMP 6.4 as well as Vdub. I fast-forward as well as rewind again and again and it's fine.

But when I inputted the AVI into TMPGEnc to convert to MPEG-2 for DVD, the end product goes out of sync. I don't know why. So now, I am using VdubMod to framserve into TMPGEnc to see if it will turn out okay.

Edit:
No, it still didn't work for some reason!

Have you checked the AVI for bad/undecodable frames? (using VirtualDubMP3Freeze)

Well, since I merged the AVI with the WAV file, I no longer have the MP3. And no, no undecodable frames. The WAV file is PCM though.

?? If you have the MP3 or not isn't relevant. But have you scanned the AVI (the one you extracted out of the MKV) for bad/undecodable frames?
How "out of sync"? "Fine to start with, then suddenly bad" or "fine to start with but slowly getting bad" or "bad sync from start to end"?

skip the audacity stage. i just save the wav in virtual dub and load it into tmpgenc as the audio source. not that this will help ur prob, but will speed the process up.

Well, I noticed that when I inputted the MPEG I made using frameserving into TMPGEnc DVD Authoring, and when I play it in the chapter creation section, it is in sync! So I burned it and the result on TV is also in sync! Pretty weird. Thanks for the help anyway.

I just got some new MKV files with MP3 sound and again they turn up out of sync and I can't do anything about it. Why is it like this?! This time, I'm not going to convert. I just want it as a single audio, no subs, AVI file.

Every time I try to do something that involves the audio in Vdubmod, it would crash. The only thing I can do in Vdubmod is extracting the AVI without audio and extracting the subtitle. I used AVI-Mux to extract the audio with 0 delay. When I merge it back into Vdubmod as an MP3, it would still go out of sync.
