OK! got the HD dtv set up working.
would have been way easier to stick with the standard def box, but hey.. once you have had HD it's realllllly hard to go back. LOL
I needed a HD dish (little bigger, oval shape, longer lnb arm), then needed a power thing that sends power to the dish. It plugs into an outlet, and the coax comes from the dish, to this power box, then you run the coax to the hd receiver, then your hdmi to the TV.
Run your set up and find a signal. Done. dtv gave me a special splitter that you can use if you use another box and want to watch different programs on separate tv's. You can watch the SAME program on a 2nd tv IF you have a special hdmi splitter. It comes out of the receiver and the hdmi splits to both tv's. He did say that some will work, some wont' and Amazon is best place for these.. read reviews of those using an HD signal before ya buy.
Question: the little $25 standard deff signal meter will NOT work with this set up, does anyone have a signal meter that does work with a HD setup ? the dtv guy indicated the one they use is like $1500 (obviously not gonna buy that).
