Okay Shane, I took a look to see what the 42H82 is, and found that it's a CRT set, which means that it doesn't use a fixed pixel screen, so disregard the parts of the discussion referring to upscaling pixels.
Yes, all DLP/LCD/Plasma HDTVs have to upscale incoming material which is lower than their 720 or 1080 "native resolution" in order to display a complete picture. Why then with such a TV would anybody buy an "upconverting" player? One reason is that the somewhat misleading use of "upconverting" leaves some(who aren't aware that the TV has to upscale if it's not done earlier)with the impression that the DVD material is actually converted to real HD quality. Another buying point is that the player may(or may not)do a better job of scaling DVD content than the circuitry in the TV itself. There's no way to say which method would work better as a generality, since TVs and players differ and each combination would have to be tried to see which was better in a particular case. Note that the scaling done by a player only affects DVDs and that the TV set processing has to be relied on with broadcast TV programming if it has to be scaled.
