In Panther I was able to open iMovie files with quicktime and Tiger won't let me open my iMovie without exporting it was a self-contained file. I have a powerbook g4 with 40GB so I am hurting for room and I don't want to create a new file with the movie. I open quicktime and try to open the iMovie. The "choose" button lights up but it then tell me "quicktime cannot open this file". I have quicktime pro. Any help would be greatly appreciated. Thanks!
