I think there was a post about this topic before, but i dont know what they were talking about.. I've encoded two AVI files with TMPGEnc and there is no audio. Whats the problem? Does TMPGEnc have troubles converting AVI files to DVD-/+R?
Its quite a common problem. There will be a solution here to it (number 7): http://forums.afterdawn.com/thread_view.cfm/40101
