POOR PICTURE QUALITY WITH NON HD PROGRAMS ON MY 46" LCD SAMSUNG HDTV?

This is one of many reasons why CRT is my favorite type of television. Fixed-pixel television technologies (including LCD, plasma, and DLP) must scale to their native resolution, so sources not at that resolution will not look as good. LCD's are particularly bad at displaying content not at their native resolution; plasmas aren't quite as bad. The only cure to this problem is to watch EVERYTHING in HD (good luck with that, that means saying goodbye to any VHS/DVD you may have) or to get a CRT (good luck finding a new one). Until about a year or two ago, they m-produced CRT HDTV's, which could perfectly display content at 480i, 480p, and 1080i with no problem, and 720p and 1080p scaled down didn't look as bad.
