I recently purchased an RCA Scenium HD61W140 RPTV with the built in off air tuner. I am able to receive HD broadcasts through the use of a VHF/UHF Antennae. Unfortunately my cable company does not transmit HD, but is in the process of BETA testing the HD cable boxes. At this point I am unwilling to switch to satellite because I also have internet access through them. When watching an analog program I can bring up the channel bar that shows program information. This tells me that I am watching an SD program in the 4:3 format 480i and whether the screen is normal, stretched or zoomed. When I switch to an HD broadcast and bring up the channel bar, it tells me that I am watching an HD broadcast in 16:9 and 720p. However, the program appears to be in the 4:3 format with the black bars on each side. Is this normal for this type of programming? Am I missing something here? I know that 720p is the best format for HD and I am impressed with the picture quality. Just a little confused here. Any help or information is greatly appreciated. Tod FYI - When watching HD I am unable to switch screen modes.
