Well, I finally got my 622 today. My official install date is next Tuesday. I already have a dish 500 pointed at 110/119 and another pointed at 61.5, which should work, and it does on tuner 1, but tuner 2 only see 110 and 61.5. I'm using the duplexer to split the one cable to both sat inputs. The 500 is using a quad and the other has a dual, all running to two 2 to 1 switches. If sat 1 can receive everything, why can't sat two? It all from the same drop.
