Alrighty, a while back I had problems burning AVI files with Toast 6, so I got my act together and got Toast 7. It worked fine for AVI's that had MP3 audio, but I can't seem to get it to burn DVD's with AVI's that use AC3. I think it may be a Quicktime related problem, though, not a Toast problem. When I run the AVI's in Quicktime, I get no audio, but VLC will play them fine. In Toast, it'll start encoding the DVD, and after about 10 minutes freeze up and quit unexpectedly. Any ideas? Is there some codec I'm maybe missing?
