I know they are the resolutions. But, can someone give me a quick and simple run down of what dvd's,tv's, hd use? Thanks! ps- I have a Toshiba 65hdx82. I remember waiting an extra few months till it came out because it had a special connection that was going to be needed...DVI/HDCP input. I also have the Infocus 4805 projector. How will either blue-ray or HD-Dvd work on these sets...If they can?
