That is weird because when I put a DVD on my (composite 1080i connected) 360, the screen swith to 576p mode (??).
Component you mean right?
HDMI is required for 720p-1080i.
Component can upscale to 480p or 576p in your case.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
