This AVI file contains two separate video tracks, one of which uses the Xvid codec, and an audio track.  The video does not use a player embedded in the browser page.

An instance of your media player software should be invoked and, depending on your connection speed, the combined video should play after a download delay of a minute or so.

If the video fails to play, you may need to download and install the Xvid 1.2.2 codec from http://www.koepi.info/xvid.html (Windows)
or via http://www.xvid.org/Downloads.15.0.html to view the beating wings.
