I am looking at 50-53" widescreen HD RPTV (Mits, Toshiba, Hitachi, or Sony). Since my viewing distance is about 6-7 feet, I was told anything bigger than 53" is not recommended. Do you agree? I had read in this forum that some new HD RPTV has such good line doublers that a progressive scan DVD players will not be needed. However, a friend told me that progressive scan players will gain advantage when displaying fast moving pictures. Is that true? If not, which 16x9 HD RPTVs would you say have better line doublers? Also, the new Sony offers memory stick slots. Won't still digital camera pictures run the risk of burn-in on the RPTV? Thanks!
