I do that all the time, watch TV and be on the web. My cable box has composite video out so it was realy easy to hook up. The Radeon videoIn allows a window on top of the desktop (which you can force on top of all the other windows), full screen or a very cool background display (meaning behind your desktop icons etc. The window is resizable to any size you want from a postage stamp size to the whole screen. Sometimes I really play hard by starting up QuakeIII on top of the desktop and play a Metalica DVD in a window forced on top, HOT MAN, REALLY HOT and a huge head rush. Since the Radeon DVD on my machine takes about 10% cpu power it does not affect my QuakeIII game play or Serious Sam game play. Its wild man and a good way to show off your machine. Just turn up the volume loud man, really loud with the in game music volume all the way down but the sound effects volume up and jam.
