Movies on this site have been produced using either QuickTime Pro or Windows Movie Maker. I’m still experimenting with these to see which one I like best.
To watch the QuickTime movies (.mov), you will need the free QuickTime player...
To watch the Windows Movie Maker movies (.wmv), you can use Windows Media Player, Winamp, or other compatible media players. If you are running Windows XP, then you should already have Windows Media Player.
