I have the 360 elite and hddvd drive hooked up to my 3752w via HDMI running 1080i . When I play hd video I notice like grainy backgrounds sometime and like sparkles and almost like snow a little bit, some scenes more than others. What is causing this? Faulty HDMI cable? I tried all 3 hdmi connections on the tv as well it does a similar thing when I played and upconverted dvd in the elite as well. I don't have a vga cable to test with and I'll try the component later but I don't really want to rip everything apart and as well the component won't do upscalling. Any tip or help is appreciated.
