But they're .avi files. I took my external over to a friend's house and got about 80 dvd rips from him. Like 2/3 of them work, the other ones have a white piece of paper for their icon (instead of the quicktime logo), and whenever you click on them it says "The Item "[movie name]" is in use by OSX and cannot be opened. Any ideas? I can't delete them or ANYTHING, not even edit the file name."
