I watched it in MacOS X [10.3.8] using Shiira (a Safari variant) as my browser, and the Flip4Mac plugin for playing Windows Media files via QuickTime.
Please, tell me more! WMP is the one piece of Microsoft software on my machines, and I would heartily approve of anything which would let me complete the purge.
The latest version of MPlayer under Fedora Core 4 Linux plays the file just fine. (You need the WMV codec, of course, but that’s available on the same page as the main package.)
There is a version of MPlayer for Windows.
A place to download MPlayer that has a graphical installer program, including codecs.
This might be better. I don’t know.
The main listing of these things. Scroll down until you see Windows.
I don’t use MPlayer under Windows so I can’t really help you, but this should more than get you started.
Well, duh.
You’re a FART SMELLER!!!
Oh sorry, I meant a SMART FELLER. 
WTF did you think I meant, my intellectuall friend across the pond?
All in fun,
In awe of your intellect,

Could have been Camel Spider! Man! Get out! OMFGLOL!
It’s a shareware plugin. You can use QuickTime Media Player (to play downloaded .wmv files) or its associated browser plugin (to play embedded .wmv movies in a browser window).
If you have QT Pro, you can do a Save As and save a .wmv as a .mov file, or a .mpg file. You can also use the “sliders” and copy only part, select and delete a part, make it loop, make it play every frame, all the usual QT Pro stuff.
