I have an RCA 16x9 Direct view HDTV. It does a great job on anamorphic encoded discs. When I play a disc that's letterboxed, but not anamorphic I use the zoom mode to eliminate or minimize the letterbox bars at the bottom of the screen (as well as the 4x3 gray area on the side of the screen). Naturally, there is some loss of clarity with the zoom mode. My DVD Player is a Pioneer, non-progressive scan. Will upgrading to a progressive scan player improve the clarity and sharpness of non-anamorphic DVDs played in the zoom mode? I haven't found a store in the area that has these the RCA set hooked up to a progressive scan player for demonstration.
