Problem uncompressing audio

[Syxxpk]

I'm having a weird problem with 1 movie. The movie plays fine but whenever I try to rip the audio it comes out very low for the first few seconds and then eventually it just becomes nothing. The audio is stored in AC3 format. I've done this process many times and it's always worked before. Even weirder is that the first half of the film (it's split into two files) doesn't have this problem. Any idea what the problem could be?
So far I've tried to rip the audio with VirtualDub and the decompress tool that comes with avi2vcd. Thanks for any help.

Give DVD Audio Extractor a try for the audio and then rebuild it w/ video in your fav. DVD authoring app.
