I just finished installing an HD receiver, i believe its the 722? at a commercial location, and i got it working fine with 110 119 and 129. i currentlly have my two cables plugged into what i believe is 119 and 129 on the LMB, which would be slots 2 and 3 if your looking from behind the dish. signals look good, but when the customer comes in the morning, it says its trying to find satellites, and goes nowhere. If he swaps the two inputs, it comes right up and is fine the entire day. when he returned the next day, it did the same thing, so he swapped them back, and it worked immediatly again. is there something i setup wrong for it not to be working properly, or is this some kind of hardware issue?
