I have 2 PC's one with XP pro, and the other with 98. I have a CD that was burnt off a mac and in some format i don't recall at the moment, but my XP won't read it. It will play on every CD player I can find including the windows 98 pc. The pc with XP will play everything else i put i it, but not this. Is this viral, hardware, software?????? HELP!!!!!!!!!!!!!!!
