I have an upcoming install next Saturday for my new 622. I currently have a 625. On the dish I have outside it says Dish 1000. When I go to system information it says Dish 500. Three satellites are listed 110, 119,and 129. On Sat input 2 for "check switch" all three are green. On input 1 it has a red X in sat 129. I tried reversing the inputs and the red X moved to input 2 and all three input 1 sats were green. Any ideas as to what is going on?
