Like you describe it, this sounds as if you are missing the right video codec to play it. This video is in xvid, a quite common format. But on some system this is not installed (yet). I would say the easiest thing you can try is get VLC Player for free from http://www.videolan.org/vlc/
. This is an excellent software which has built-in support for many audio and video formats, and which is good to have no matter if you want to play this specific video or not.
(You can also download the xvid codec manually from www.xvid.org
, then it should play in Windows Media Player and Real Player.)
Thanks again Neely. I got it to work.
