I am looking at upgrading the TV in my Family Room, but don't wish yet to get a 16:9, as the majority of programming my family watches is still 4:3. However, I do still want a HD-ready set. I am looking at 2 32 inch tube televisions at Best Buy, the Sony KV-32HS420, and the Samsung TX-P3271H. They both look great at the store, the Samsung being $100 less. My question is: Since it's a 4:3 set, does it automatically go into a 16:9 mode when receiving HD content and put in the black bars, or does it stretch it to to 4:3? I'm hoping somehow the sets know, and will keep all SDTV 4:3, and when sensing HD, make it 16:9, but I don't know. Thanks!
