I have an RCA DTC-100 High Def satellite receiver that I currently watch standard def (upconverted) and high def programming through. I have always wondered if I am getting a better or worse picture on standard def channels through the DTC-100 than I would by using a HTPC. Can anyone comment on how the the DTC-100 compares to a HTPC with say a MyHD card. Right now my HTPC does everything except TV for me. Any reason to consider changing?
