No, it has not been completely answered.
As this person said, he or she has a Phase II dish. A Phase II dish has a built in 4x4 multiswitch that resides in the three lnb adapter at the end of a lnb arm.
It automatically has four outputs that can be used to go to two DirecTivo's, with two outputs going to each DirecTivo. I haven't seen a PhaseII lnb in a long time, but as I recall, if you remove the vertical through stove bolt that holds the adapter to the lnb arm, you will see four cables. These are the switch outputs to which you need to connect the receivers.
I know for sure of one 4x8 multiswitch that will work with a Phase II dish, in case you need more than four outputs. That switch is the Zinwell SAM4803.
