GOM Player

This is a great player for your video files and has lots of configuration options. GOM Player supports most common video codecs, including DivX, which are embedded in the program so do not have to be downloaded separately. It is claimed that GOM Player can play "broken" AVI files and files that are being downloaded, but its major plus is that it is very, very easy to set up playlists (unlike with Windows Media Player). It also looks good!
