I recently upgraded from panther to leopard. I checked all the apps to see if they worked and everything was good except for my iDVD 5. I just get a black screen with no images of any sort. I don't really want to get iLife 08 because my processor is just shy of the needed requirements for iMovie. So i don't really want to shell out 80 bucks for software that i can't entirely use. Any ideas?
