Hi. I am really frustrated here. I have a rather new Mac Book Pro and am using Toast 7 with latest updates. When I burn photos to a DVD, I indicate "Mac & PC" in the set up. I burn the disc, it verifies and ejects. No error messages. However, when I attempt to playback on my PC, nothing shows up! The disc is not even recognized. I have tried two different DVD drives without success. The same happens when attempting to burn photos to CD. I am hoping there is simply some setting that needs changing or something. Any feedback is GREATLY appreciated!
