I think you're missing the point... I don't need a burned cd to play the music on my computer, I just go straight to the folder with the music and use VLC to play it direct. According to what I've read online, a copy is in my previous post, a cda file doesn't contain the music data. It's some weird link that Microsoft create. If the actual music isn't on the disc then it won't play in my mate's car.
What I don't understand is why every program I use keeps creating discs with a cda file and not the actual music track.
