stretched....the HDTV makes it kinda like partial zoom. Pic looks good and when I watch a SD hockey game they dont look like fat midgets 

I used to keep the 4:3 with black matting on my first HDTV.
Years later the black matting BURNED into the TV, distorting the color on full 19:6 HD features.
My new HDTVs are either partial or full zoom, but occasionally I leave the OAR which I prefer.
Not to be mean but that is your fault for buying a plasma TV. Plasmas are always junk and only uneducated TV people buy them. They have screen burn issues, use a lot of electricity and limited life spans since they rely on gas. When the gas runs out all you can do is throw away the TV.
I second your opinion. I can't stand watching SD anymore.I dont watch any SD channels anymore or SD programs for that matter.

I will do normal (pillar box) or stretch depending on the show. Letterbox SD shows on an HD channel, like Doctor Who, I will zoom in.
My wife HATES any kind of bars on the screen. Not only will she stretch SD channels, she prefers SD channels over HD so that she doesn't have to mess with the settings. We just got a 612 for the HD set in the bedroom, which is where she does most of her TV watching. All of the channels on her favorites list are the SD versions, except for the movie channels. Since the movie channels are usually zoomed in to fill the 16x9 screen that works OK for her. She even prefers to buy fullscreen DVDs so she won't see the black bars on OAR widscreen movies.
