Video file changes desktop resolution

  Bad Dad 20:05 27 Jun 2004

When I open a window of a directory that contains a video file(MEPG), without running the file, the desktop changes resolution to 800*600 with a refresh of 60hz. This is somewhat annoying. Does anyone know how to stop it doing it. I've reinstalled drivers etc etc, changed the file association just in case the program that used to run them, Win DVD 4, was just trying to be helpful but with no results.

Any assistance would be most welcome.
