DirecTV H-10 with an all-digital plasma large screen. Three SD regular TV's in the house, hooked up to the same dish outside with a Terk 44 dish antenna and diplexed at the back of each of the four receivers are able to pick up all the analog stations. Yet on the digital TV, only digital stations come through. How can I get analog channels (like analog channel 5, not digital channel 5-1) to come through? Since not all local stations broadcast in digital here (and we don't get locals through satellite yet), how can I get the regular channels on the digital TV? I'm getting desperate. Thanks in advance!
