I have an .avi movie which had AC3 audio (Dolby Digital), I used ffmpegx to turn it into .mp3 audio. I can watch the movie no problem in quicktime on my computer - but when I use iDVD to encode it the sound stops after 5 minutes of play at the same point everytime. I have tried saving it as an image file and then burning it with Toast / Disk Utility but its the same deal, somehow once I use iDVD to encode it the sound is done after 5 minutes

Does anyone have any ideas whats going wrong?

Thanks!
