Do you have a favorite movie you watch over and over again to the point it's become more than a little OCD?  If you haven't thought of it already, you might consider converting it to more than one format. That way, you can watch it on the road, at the Doctor's office, at work on lunch, family dinners and even at the movies. Furthermore, chances are you have more than one media player. Among the players available, few if any have a common format. If you are a true fanatic and must have your obsession on every one of them, then WinXDVD is probably a bit of software you should be interested in. Even if you're only interested in copying a movie to your psp or to an .avi file, you'll probably want to read on about it too.
