QuickTime Folder Player
This patch (when saved in a folder containing a bunch of Quicktime files) will automatically play each movie, one after another. It uses the 'loopreport' attribute, which causes jit.qt.movie to send the message 'loopnotify' out of its right outlet whenever it gets to the end of a movie (actually when it gets to the end of a loop, but by default the loop is set to the entire movie).
