Damofr, I am experiencing the same thing on my new HDTV. It's a Samsung, 40", LCD and I'm using Wii component cables. Zelda looks really bad but Mario Kart Double Dash, a game cube game, looks great. I just don't understand it. All I can say is try different settings on the TV and match them with the settings on the Wii and see what looks better. And people, we are not talking about poor graphics, we're talking about poor picture quality of the display on some Wii games. Anyway, I'm in the same boat and still trying to find the answer myself. So you're not alone. Let me know if you discover anything and I'll do the same.
