I asked a question in the Gen. Dish Forum about this same thing (sorry for the dup, but thought the 921 group would see it better here).
If I use a DPP44 switch to hook up 3 dishes (Dish 500: 110/119, Dish 300 for 61.5 & 148 -- all using DishPRO LNBs), I KNOW that I can hook up this switch for all 4 orbital locations (61.5, 110, 119, 148). The question is will the 921 recognize this configuration and will it "work" (I know about duplicate channels in the EPG such that you can't channel up/down across duplicates, but will the 921 otherwise work)?
