Hey guys. I just changed my multiswitch from a 4X2 to a 4X4 to accomodate adding a Tivo. My problem is now I get perfect readings on some transponders and 0 on others. I need to know in ya'lls experience, is this a bad switch or was I clumsy and knocked the dish out of alignment. It is a high def dish and directv was no help. I am getting some channels on all three boxes, but not all of them. TIA for your help.
