So when I had Leopard 10.5, I used to use Save Hollywood as my screensaver application. What that does is transform any video file that you have in a screensaver. After Snow Leopard came out, Save Hollywood no longer works... I don't know what else to do, that was a must have for me and it is starting to frustrate me. Is there any other software that would allow me to use a video file as a screensaver that would work on Snow Leopard. Has Apple fixed this issue on 10.6.3?
