By the way, if you are still using an old way of watching movies from the web, which involves downloading a film and than playing it or associating the file extensions with some programs, than you should try the mplayerplug-in. After you install it, your Mozilla browser (yes, that includes Firefox) will play all sorts of movies in a small part of your browser. You will also be able to control it with usual slow motion, pause, rewind, fast forward, and stop buttons, as well as toggle fullscreen mode. Download either a compressed TAR archive, or an RPM for your version of the Fedora Linux. Screenshots are also available from the site.
