I have an older XBox 360 (no HDMI) and the HDDVD add-on that I have been using with component cables. I've had an older HD TV set with no HDMI, so it has worked just fine under those circumstances. But I've just purchased a new 1080P TV and would like to be able to play my games in 1080P and also watch HDDVD movies in 1080P. Is there anything I can do to my current 360 to make this happen??
