I am shopping for a little module for the Wii, its an HDMI adapter which up-scales the Wiis 480p Signal into 1080p (not true HD, but looks nicer on an HDTV). Now the US Wii does not do RGB at all, but the PAL models do. Does anyone know if the PAL variations of these HDMI adapters upscale a RGB input or do they all just upscale the plain progressive image.
