Trouble Demuxing AC3

[sammie]

Never seen this one before. I'm backing up some old TV episode DVDs. Rip is fine. I've extracted the individual vobs and if I copy the vob set onto a DVD it plays fine. But I want to set up a menu screen and burn about 4 episodes per DVD. The problem is I can't demux the audio from one of the episodes. Vobedit just get's 18 seconds of noise. DVD mediator gets all sorts of different lenghths, but never more than 95% of the audio, DVD2avi gets consistently a bit over 1/2. I give up, anyone have any idea what could be wrong and how to fix it?????

have you tried doing it when you rip say with decrypter.

I didn't do that, mostly because I've never had any problems with Vobedit. It might be tough to try now , but I guess I could try "re-ripping" the existing files.
