Everybody is looking at the same satellite so it doesn't matter where you live.
Sounds like you have one line direct to each LNB with no switches in between.i also try to plug the two direct line in result: tuner 1 see only sat 91, tuner 2 see only sat 82
Wasn't sure if he got that part when said plug and play with the cables.If I upgrade the lnb's with the new DPP twin as you suggested, is it a plug and play type of scenario - leave the dish pointed in the same direction, bolt on the new LNB (provided it fits the current arm on the dish), connect the cables and everything should work?
