Any HDTV can receive and display SD programming. The only issue is that SD programming is broadcast in 4:3 format (the aspect ratio of your old TV), while HDTV's are in a 16:9 aspect ratio. Therefore SD programming will appear on your 16:9 TV as 4:3 so you will have black bars on both the left and right sides. You can however, choose a zoom function on your TV remote that will stretch the 4:3 image to fill the 16:9 screen. There will be either some squashing or stretching or loss of edge image when you do this. If you hook a DVD player up to the new HDTV by using an HDMI cable (preferred) or component cables, most DVDs will fill the screen if they are new material that is produced in widescreen. An old TV show on DVD (like Adam's Family, Green Acres, Get Smart) and some newer shows will not be in 16:9.
