I was doing a quick calibration of an HDTV today and I noticed the Nintendo Wii was hooked up using the Composite Video cable (yellow/white/red) that comes standard with the game.  The Wii video will look a lot better on an HDTV if you use the optional Component Video cable (red/green/blue, red/white) available just about anywhere Wii’s are sold.  Fry’s had one advertised this weekend for $14.99.  After you hook up the cable, use the Wii’s settings menu to enable 480p and 16 x 9 aspect ratio.  Thank me very much.
