Alright, so I am a little confused about this receiver, its sibling (863), and the v1800. My concerns are about upscaling video. From reading all 7 pages here, I understand that the 663 does not improve the resolution of any analog source (it simply sends it via HDMI). But, does the 863 scale up the resolution at all then? I had settled on the v1800 over the 861 until this morning when I saw the new 863. I have athena technology speakers with a Panasonic Plasma, PS3, PS2, and an Xbox, and am running with a htr-5960. Teach a newbie...pleeeeease?
