I posted a message about this, but still haven't received a definitive answer. I have a 3 x 4 multiswitch mounted on the roof on a DTV+ dish. All four lines are being used. Two of them go into a Tivo receiver. Would I be able to take the two lines from the Tivo, put them in the inputs of another 3 x 4 multiswitch, then run two lines from the output of the second multiswitch into the Tivo and run the other two into a new receiver? Would I pick up the channels and would DTV be able to recognize the new receiver?
