Some of my movies are broken into 3 or 4 files as commond with dvds. When I play the files some will display in a full or wide as they're supposed to. While other from the same movie will show with black bars both on top and the sides. Files are from the same movies but different segments. Under windows properties and mezzmo properties the files are 100% identical except the name of course. Even the thumbnail created shows up with top and bottom black bars.

Any suggestions?
