So, I'm putting together this DVD. The main video file I have is a 1.2 GB .avi file. I wanted to edit it a little before I put together the menus, etc. in iDVD. I imported the video to iMovie to do the editing, and it got to 99% and then crashed. I haven't tried again since, becaues it took a couple of hours to get that far, and I expect the results will be the same. Any advice?
