Stand-alone DirecTV multisat switches are 22k switches. A real nice setup for more than two receivers is to use the Invacom QPH LNB (circular and linear) in conjunction with a 4 x 4 (or even 4 x 8 if you need that many receivers) multiswitch.
Consider the circular and linear sides of this LNB as two separate dual-output LNBs. Connect both outputs of one side (either C or L) to the two 0k inputs and both outputs of the other side to the 22k inputs on the 4 x 4 switch. This connects all four outputs of the QPH (the two circulars and the two linears) to up to four independent receivers. The 22k 4 x 4 switch works well with the Quad Polar Invacom LNB because the linear side is NOT universal but standard (L.O. 10750). In your receivers satellite setup menu, select either 22k on or off depending on whether the satellite is circular or linear. So, instead of using a DiSEqC switch, you are using a 22k switch.
Of course, only one receiver can control your motor, so all others will only be able to watch programming on the one satellite your motor-controlling receiver is on. On that receiver, run cable from the receiver to the motor, then from the motor to one output of the multiswitch.
