What's the theory behind the 120Hz displays scaling SD so much better? I thought the intention of the higher refresh rate was to fix motion blur, which I've never noticed on my small LCD display, and also to fix deinterlacing issues with 24fps source material. (Which I've never looked for, as I don't own any HD disc players, but I doubt I'd notice anyway -- the extent of my video snobbery is solely hate of overcompression.) I wonder if the new sets have really managed to implement some sort of smoothing which can deal with compression artifacts.

When I was in Circuit City over the weekend trying to decide whether I could tolerate a 42"+ LCD with Dish's SD compression, the salesman told me that plasmas didn't show problems as bad as LCDs. But when he switched the sets to an SD local channel from DirecTV (it was on ESPN-HD, which didn't look so great either on the really big sets), they all looked uniformly terrible.
One unknown here, however, is the issue of whether the sets were being fed with 480 signals or whether the channels were being upscaled by the receiver. I didn't ask because I figured the salesman wouldn't know, and I have no idea how to navigate a DirecTV receiver. I know Dish doesn't have native resolution passthrough, but I've seen a lot of people recommend using composite for SD channels to let the TV do the scaling. I haven't tried it yet because the back of my receiver is hard to get to the way I have things set up now, but it seems like it would be a major annoyance to switch inputs every time I switch channels.
I'm pretty concerned with this issue. Right now my 622 is feeding a 27" SD CRT and a 21" HD LCD. I'd really like to upgrade the 27" CRT sooner rather than later, but I want to go with a large enough set to make it worthwhile while also not spending a lot of money. As it happens, Vizio was one of the brands I was looking at because people on another forum seem to mostly agree that they're the best of the low end and can give a semi-respectable picture by calibrating them to sensible levels instead of the blown-out level the stores put them on.
