Is there a receiver capable of HDTV that has the built in Tivo or Ultimate TV? A unit that would record digitally an HDTV signal and then play it back as HDTV would interest me greatly. So far all I've been able to find is HDTV units and regular DirecTivo types. I just purchased and set up a Toshiba 57HX81 and now see just how horrible the signal is on my analog cable from Time Warner. The decision on what satellite system and equipment is upon me now.
