Default audio out of sync

I have part of a vob file I want to edit out. I have tried a couple of different ways but the audio always gets screwed up. First I converted to avi with Xmedia Recode, then edited it with Avidemux using stream copy (not full processing). I also tried directly opening the vob with Avidemux, editing and saving it as mpeg. In both cases the audio didn't match, in the second instance I could hear audio from parts I had edited out being played.

Try VideoReDo.

If you want to take another shot at a freeware solution you can try
http://www.videohelp.com/tools/VOB2MPG

and

http://www.digital-digest.com/dvd/downloads/showsoftware_tmpgenc_412.html

Depends on how fine an "edit" you need. For cutting out a coarse chunk you may be able to get by converting the vob to mpg using Vob2Mpg, then the MPG tools in the File Menu in the old free TMPGEnc. In MPG Tools select from beginning up to the chunk you don't want and do Simple Demultiplex. Then select from the end of the chunk you don't want, to the end and do the same. Join the 2 pieces using Simple Multiplex. Note that although the free TMPGEnc doesn't support AC3 encoding, the MPG tools will demux and mux ac3/m2v files.

All this assumes you are running XP. For Vista and W7 I'm not sure the free TMPGEnc will run or install using compatibility mode. But you can always use the new TMPGEnc Plus 2.5x 10 day free trial.

Thanks, I think a big part of the problem might be that the original audio is VBR mp3. I tried converting it to mp2 but it didn't seem to solve anything.

paglamon may be right. Have you tried the VideoReDo 10 day trial?

VideoReDo seems to be working great so far. It does fast stream copy without full processing, yet it doesn't seem to be limited to cutting only at keyframes, it seems to allow cutting just about anywhere. Is that possible?

Yes, it's its major advantage over most other programs of the same kind. It re-encodes only the GOPs that have been cut, and keep the rest unchanged as far as possible. That's great to remove commercial from recorded TS streams.

Another tool that can do the same thing is Womble MPEG Video Wizard DVD. It can also add transitions between segments, but it has a lot of bugs and its GUI is terrible. IMO, VideoRedo is better, although more limited.
