To have Eclipse display QuickTime movies, the QuickTime extension needs to be installed on your system. Without this extension, QuickTime movies and graphics in the JPEG format can't be shown; Eclipse skips them.
Another reason Eclipse may skip movies is due to the fact that Eclipse doesn't see the file as a QuickTime movie. Some applications will write code to a QuickTime movie that plays the movie when it is opened. This changes the movie to an application. Eclipse will not recognize the file and will skip over it. You can check this in the Get Info... window. The "Kind:" of file should be "QuickTime movie."
