I just got a new iMac, upgrading from a 2006 Intel iMac. Anyway, I was just going through old files and came across my iMovie files. I was sad to find that many of my older files won't open at all, and the ones that do have all their video effects deleted. What gives? I can't even find anywhere in iMovie 08 that allows for fast/slow/reverse of video! I was initially excited by the new iPhoto-esque UI, but now I see it seems to have actually been really dumbed down!
