HDTV and non high def content

[larrym64]

I recently returned a Sony KDL46W3000 because when I was watching non high-def content the picture was worse than my 20yr old 27 tube.I was wondering if anyone has any suggestions for me. I ask this because not everything is broadcast in high-def so what is a person to do when not qatching high-def. I had the proper sattilite box and caable box and was using a HDMI cable. I am now considering the Sony xbr4 or the Samsung 71. But for me the non high-def picture has to be at least as good as my old tv. I am assuming that it was not the TV as when I had the Blu-ray on the picture was beautiful. Any suggestions would be appreciatted.
