I still can't figure out my problem, and I've tried most stuff I can think of. I've never had this problem before, so something got changed somewhere. When I convert from avi to mpg, and play on either of my different model apex dvd players, the audio is choppy (goes in and out). When playing on the computer, it's fine. I convert it at audio layer 2, 44.1, and 224 bit with tmpg. If anyone can offer some suggestions, I'd appriciate it.
