"An interesting curiosity, if you play the CD32 commercial from the Demo CD version 2,and have the FMV installed, you get full screen MPEG, but without it, you get CDXL playing in a small screen about 1/4 of the size. It took me a long time to get one (eBay), and I got ripped off on a dud one first."
