Advice Sought

I will be soon chging residences...and will have to do away with my separate 5.1 system as I have one less room and do not want to "combine" with my 2 channel set up. Also overtime I find I just use it for really watching DVD movies and thus the value proposition to me now is much more heavily towards video for this sep set up. I know what I want to do with regard to sound set up (either Yamaha or Polk surround bars + my existing ML sub to save space etc). What I need advice is on the video set up. My old Fujitisu 42 inch plasma will move to another room as will be DVD player...want to upgrade. Its been awhile since I've investigated video so I am quite behind.

Can't have a projector set up so it will need to be LCD, Plasma or DLP rear projection TVs. Size would prefer 50 inches and above but no need for those huge 60 inch plus screens. For DVD, no need for SACD, DVD-A, and I will not be using for redbook CD play either: audio quality is confined to playing movies. For both the paramount thing is video quality, including correction for artifacts, upconverting (no HDTV where I live but I understand upconverting to 1080p improves DVDs? Not sure what the difference btwn DVI and HMDI and whether I need either or both) but also the basics, richness of color, clarity of detail, depth imaging, wide viewing angle if possible, good blackness (and also quiet in terms of noise). HD Video, Blu Ray I will deal with when they do come. Price is not an issue,..willing to burn.

Any recommendations? What would be the "best" in your opinion?
