I have been playing avi files on my pc and when I burn them onto a dvd they still play ok. The problem is when I play them on my Pioneer DV-575A the backing track is ok but any speech is really muted. It does'nt happen every time and the only differance I can see is the audio bit rate of the files. The ones with a lower bit rate seem to play ok. Is ther a work round this? I don't really want to have to reconvert my files. Any help would be greatly appreciated.
