I made a simple movie of still pictures (scanned) set to music. However, when I try to save to CD it says that files have been moved etc. Although I may have re-named some of the files/pictures since I first began the movie, I KNOW they are still on the hard drive. Why can't movie maker find them? How can I find out WHICH files are missing?
