You'll need to open the movie with an API that understands the movie file format, and which can extract single images. You didn't say which format that is, but QuickTime can read quite a few. The JMF API from Sun may also help, but it is no longer actively maintained.

It looks like JMF can't handle the XVID file format. I don't think there's anything you can do about that, and I've no idea if QuickTime supports XVID. The easiest way to find out is probably to try and run the video through the QuickTime Player application.

Are you sure that the movie is fully loaded? I'm not familiar with JMF, but maybe you need to use a mechanism like MediaTracker to determine when the image/movie is fully loaded.
