The 811 has two inputs on the rear panel in the form of RCA. If I use those inputs for my xbox and ps2, will the 811 upconvert those signals? My delima is my HDTV (51 inch Sony Rear Projection) only has two Composite Video inputs and no DVI. I have 4 pieces of hardware in which I would like to use the componet cables. (DVD player, 811, XBOX, and PS2) Any help would be appreciated
