The XBR450 also progressive scan inputs. I own the KV32XBR400 I am very happy with it. My signal source is a RCA Directv reciever conected via Monster Video3 S video. This television looks great with HD brodcasting and DVD.
The XBR450 has 2:3 pulldown which the XBR400 and HS20 do not have. This is suppose to provide fewer artifacts and cleaner pictures with NTSC sources (The Perfect Vision July/August).
