There is a program called streamboxvcr that you can search this site for (there was an article about it a few days ago). I can't explain how to use it though as it is somewhat complicated (you need a crack because it is technically illegal). I think the page this site links to is: http://www.geocities.com/streamgen/streambox.htm
Go there and if you are motivated enough you can figure out how to use the program and record your clip. There might be an easier way but not that I know of.... hope that helped.
