Hey, I just got a HD Wii connection from GameStop and I can't get it to work. I hooked up all the colors, light red, blue, green, white, and dark red, but there isn't a place to put the yellow video cord. I just left it out to see what happened and the picture and sound came, but the picture was black and white. I plugged in the yellow video cord into every yellow input, but they were all for different channels. Does anyone have any ideas?
