would all fit on cd, but I can't play the files, why? I can't get any programs on my computer to play the mp3 files that were burned to the DVDR. I even copied one of the files from off the DVDR to the hard drive, and it still won't play. Any solutions, or reasons for this?I found a couple folders that contain music that plays ok, but the music in the other folders isn't playing. It shows that they all burned, and the they are the correct size, etc... but not playing.
