I created a VCD slideshow with music using Windows Movie Maker for my girlfriends Pre-K class year slide show. The VCD played fine on my "PC" and on my TV. She took it to school and told me later that the VCD didn't work. I said what are you talking about i tested that thing. She said when I put it into the "MAC" lab top it didn't work !?!?! My fault for assuming she was going to use a PC. I didn't know she had a Mac in her classroom. Anyway, it it safe to assume the a Windows program wont work in a Mac ? And does Mac have a similar program to Windows Moviemaker that is "Free" to download as i may have to redo the slide show. Thank You !!!!
