Aha, here is your problem. All 4 lines from the dish need to go to a 4x8 switch which then would distribute the signals to all the receivers.magellanmtb said:
An individual tuner can be asking for signals from 1 of 4 sets of transponders:
Sat. 101, odd transponders
101, even
110 and 119, odd
or 110 and 119, even.
The switch forces each line from the dish to a known set, so it needs all four to pass on to the tuners.
Call D* and have them upgrade you to the new 5lnb dish with a new 6x8 switch for the 5lnb for free (ok, you might have to pay shipping).
