Or (if you can find one) a DPP33 switch. I know for a fact that a DPP33 can accept DP LNBs (including the DP twin) and output 3 DPP lines. I had one in operation like that with my 3 VIP DVRs for years until Dish replaced my split-arc setup with a 1000.4.
My Hopper system is set up with 2 dish pros,2 single lnbs for 110 and 119, a single lnb on other dish for 129, not sure what DP switch I have now,before Hopper I had a DP34.
Correct, the Hopper system can connect only to a single integrated DPP LNB assembly (with associated wing dish) or a DPP switch with multiple DP or DPP LNBs.
