I'm not an expert either but you do need a new HDTV DSS receiver with elliptical dish to receive HDTV broadcast. This receiver will work with the analog tv or with HDTV set. I believe Hughes has a system called DSS II now that is for sale for this very purpose. It has an 24" elliptical dish, but I do not know if the receiver is HDTV ready. For more info, follow this link
