It's really not going to look any better than 480p, no matter which one you buy.
yeah I know.... I need one of those because the component reciever of my LCD doenst work with my wii (the screen just goes black everytime I turn off the lights... haha really weird). So the only way for me to have progressive scan is via HDMI.
I want to buy one of these adapters but I dont know wich actually works like it should (clean 480p signal, with wii games, interlaced gamecube games and interlaced wiiware games like megaman 9)
