Hi, I've had regular DirecTV for more than 6 years. I ordered a new DTV HDTV system for my new HDTV and the installer comes on Tuesday. I have some questions for others who have upgraded. First, can the existing wiring from the dish be used? The last time, the installer wouldn't go the extra yard to run it into my attic and drop the cable into a wall behind the TV. I had to hire another person to do it. Second, what connections from the DTV HDTV box to the HDTV provide the best picture/sound? Right now, it's just cable, not RCA jacks. I also have a DTV box for another TV. That one is not HDTV. Can you have 1 HDTV setup and another analog from the HDTV dish, or do I have to leave the original dish up? The system I bought also came with a HDTV antenna for OTA. I live about 20 miles directly west of the towers but live on a lake which is 2/10ths of a mile down a hill. I have a feeling the trees will block the signal. Is the antenna provided a powerful one or is it weak? I know my terms may not be correct but any help is greatly appreciated.
