The patch does *not* replace the movies. You need to make sure all the VOB's are in a folder within the prophecy folder called "movie". Note that it is *not* named movies. If they still don't play, also check to see if you have the latest version of the Prophecy enhancement pack. About the crashing, this sound similar to what happens with the WCIV DVD if you have PowerDVD installed. Was it crashing before you installed the patch? Does it do the same thing with a fresh install and only applying the compatability mode?
