After reading the top of the thread, I was just thinking to myself how you even had component cables as my Wii doesn't, just the composite ones...........why do you need a new cable though, what happened to the one in the box?
Yeah one of things that annoys me about the wii is how primitive its display characteristics are, on a 50" screen the picture really is quite poor.
Wii only ships with composite cable (One vid cable (yellow) and stereo audio cables (red + white)) - therefore no HD and rubbish picture on HD tellies.
Composite cable (sold separately - 3 vid cables + 2 audio) will allow Wii to display at 480p - not exaclty HD but passable on HD tellies.
No real HD on Wii until Wii HD (the refresh console).
