for the past few weeks i've been having the same problem:
I convert AVI files to VOB files with NERO VISION EXPRES, and then burn them to a DVDROM with NERO.
The only problem is that, after i converted the AVI to VOBS, the audio isn't synch.
It's ok in the beginning, but after a while, the audio is ahead of the movie, so i hear voices, even before i see the mouths move.
I know this is called stretched audio, but HOW DO I FIX IT.
