I recently bought a 27 inch HDTV (Samsung TXM2796HF). I am mostly wathcing regular cable on it. In a case like this would a non HDTV of the same size look better? I ask because to me the picture looks bad. It is sort of blocky/pixelated especially in areas of solid colors. Kind of look looking at a picture on a computer monitor if you have it set on a low number of colors. II read some stuff about HDTVs showing the problems in bad cable signals, but it looks pretty much the same when I am watching a DVD from a non progressive scan player(composite hookup). So am I nuts thinking it looks bad? The salesman told me it should look better than a regular TV even on analog signals because of the line doubler? The reason I ask is because I am thinking of returning the set and getting a flatscreen analog of the same size. Extra cost isn't a consideration since I bought this TV on an open box discount for only $450. So would I be better off with a 27 inch analog for the same price?
