there is the link right there in that page.
It didn't work for me, but I think it is becuase i have the wrong version of WMP on my computer.
I am not sure if you can download it becuase it is streaming. If you have the hardware, you could set up a TV as a second monitor and use a vcr to record the video. Any other ideas?
