Ok the problem with the sound is that the audio codec i was using is not compatible with my dvd player, i converted the file with another audio codec and it now works fine.
Jedi_Bowler just a question, is all your collection from StrikePass? Also what sort of file size and format have you saved them in? I'm currently using ucfrtc to convert to .avi, but for about 1hr 30mins file size is around 700meg.
