Just wanted to know if that worked, I am also having a problem editing in IMOVIE the video shows in the library but once I click the video I get no matching video. I also contacted MAC support they were unable to find the solution to this problem. If someone knows please share. As stated the video is in the library but once I click the video it states no matching video. I also search in IMOVIE folder and the video.mov shows in the folder but still wont open in IMOVIE.
