I currently have a round dish and a RCA powered 3 x 8 multiswitch with 2 wires in from the dish and 6 out going to 1 standard TIVO and 4 other standard boxes. I'm going to buy one new HD receiver to replace one of standard boxes and I'm getting a triple LNB dish installed to replace the round dish. I understand that a triple LNB dish has a 4 x 4 switch built in but I have more than 4 TVs. At this point, I really only need the new HD receiver to see more than the 101 sat so do I need to upgrade my multiswitch to 5 x 8 or can I somehow wire through or around my existing switch to get the new receiver pick up HD? I don't care if my TIVO and other receivers continue to pick up only the 101. Any advice would be greatly appreciated. Thanks.
