I play my Wii on component cables made my Mad Catz. In several games I see a flashing black slightly translucent bar across the top of my screen. Sometimes it flashes for only a moment, but during certain situations (the Mii creation size/weight screen and the name screen for instance) it stays up there the entire time. If I switch to say eyes or mouth the black bar goes away. Another example, on Warioware the black bar only appears during the screens with the soft music that explains the wiimote instructions. Otherwise the game appears fine. It seems to happen more visibly with white backgrounds. Any ideas?
