I made a 3 minute movie from a selection of video clips a couple weeks back and saved it to my external hard drive. At the time everything worked perfectly. However I just plugged in my external to boot up my imovie HD project and opened the file and next thing I know im in iMovie HD and when I play it there is no video.....It is just a white screen where the video should be playing. The audio to my movie works fine, and it shows that the video clips are still there in iMovie. But all I get is a white screen? Anyone know what to do about this P.S. When running my DVD project that is from this, iDVD crashes when previewing my DVD.
