I think this has been covered a few times... The only response I get from the usenet newsgroups is to try another program. The fact is I shelled out $100 for this and that is not an acceptable solution.
So here I am. Using Nero Vision 4, and I get the same thing, but not on every file I burn. I burned three files onto one DVD, the first one was OK, the second one has major audio syns problems and the third one was minimal, but was progressively worse as the show progressed.
Each file is xvid, and here are the specs.
There HAS to be a solution.
