when i get to the end of the movie (in quicktime) i have to go back one frame to see the next "layer" and manually rewind to view the scene.
What do i need to do to view the whole movie all the way through?
And what causes this?

Use VLC to play them. It's caused by people incorrectly combining multiple MPEG video clips.
A simplified explanation would be that the MPEG header at the start of the file tells QT how long the file is, so it plays only that length, then when it gets to the end of that clip, it reads the new header, but since it's already done playing, it just stops.
If you want to fix it permanently you need to demux the MPEG file and remux it (you can use bbDemux to demux it and MPEG2 Works or ffmpegX for remuxing).
