I have been able to read CDs I have burned under Jaguar on PPC 7500, PPC 8500 and performa 6400's. I normally used Toast but IRCC, I did do some with the built in burning capabilities of Jaguar. Have you tried different media? I recall some other users having issues with some of the cheaper CD blank media available these days. Although I have not run into any problems with any of the various blanks I've used. The CDs that you did in Windows were the same media as the ones burnt on the Mac? Which hardware are you using to burn the CDs?
