Hmmm, that's really interesting, but I don't think they install a driver. Have you checked the driver list your system can provide?
Last time I checked, copy protected CDs were 'normal' Audio CDs with broken Table-of-Contents and an additional Data track that contained encrypted mp3 tracks and a player that could decrypt those mp3s. (Okay, I didn't really look at one, I just read that in the manufacturer's description...)
