Advertisements I apologize if this was asked before - I searched but couldn't find a similar question... I have a DirecTV Tivo (Samsung Unit and a Phillips Unit) units. I am planning on purchasing HD TV and HD Dtivo DVR within the next 3 months. Now the question. DirecTV will be servicing our system in the next few days (they serviced our units today but did not hook it up properly (They replaced a multi-switch but cut and misconnected coax cables causing one of our DTivo's to be missing a Tuner). When they service again I was going to have them install a 5LNB HD Dish hooked it into our SD DTivo which is hooked into to a SD TV What is the down side? Will the SD DTivo's work? I assume I won't see the HD channels which is fine or If I get the HD Dish, HD DVR and feed it in an SD TV would that be OK? My purpose here is to save time later - I don't have to wait for DTV to install later. I can just put in the HDTV and a Weaknees DTV DVR? What do you think?
