audio vob

[point_vector]

I recently ripped the audio from one of my dvds that I made none the less. Anyway, the audio is in the lpcm format, but when I ripped it from the dvd, it's now that .vob and I can't do anything with it. I need it to be lpcm again without loss of quality. Could someone help me out? I tried using virtual dub, but I get an error because there is no video. I plan on capturing the video later again, so I didn't rip it. I also tried to use tmpegenc, but it crashes, any suggestions
Thanks
