Okay, I have a 5x8 multiswitch that I am going to install this weekend. One of the inputs is for cable TV. I assume that this means that the cable TV signal will be diplexed with the Directv signal on all the outputs. I only have a need for cable and SAT in 1 or 2 rooms. For the other rooms, can I just run the output of the multiswitch directly into the receiver, or do I need a diplexer for each output to split the SAT signal back out? It seems to me the the receiver would just tune the freqs it needs and ignore the cable signal, but I just want to make sure. Thanks.
