I use multiple monitors and often have a Channel 9 video playing on one of them while I work. I finally got tired of using the WMV links to get a real full screen player that wouldn't close when clicking on another browser window, so I created a bookmarlket that resizes the video player to use up the whole width and height of the window. It inserts the player at the top of the page, so while it is playing you can scroll down and read comments or open the links. If anyone else is interested in using it you can find out more information here:

Enjoy!
