I have a set of files, some with Xvid and MP3, in an .avi file, which work fine in a DVD player, but for some reason, some are .mkv, with MPEG-4 and AAC. I'm going to demux them and convert the audio, and remux as .avi, but I'm hoping I don't have to alter the video codec, and I don't want to waste a disk to see if it will work.
While I'm asking, if a DVD player plays MP3, will it play AAC?
