I just switched to an iMAC and I can't figure out how to make CD's for my clients who have a PC? When I go to burn the cd from iphoto folder in my Mac it makes the CD but then it won't play on the PC of my clients. Is there something else I need to do with Mac. I never had this problem with my old PC. Any help would greatly be appreciated. I need to figure this out fast as I have 7 client CD's I need to get in the mail this week. Thanks so much!
