I have a Dish 1000 (Twin LNBF and Dual LNBF) connected to two DVR receivers (VIP 622 and 625). Both receivers are connected to second TV and thus I have 4 TV connected. I want to add a third 311 receiver to a 5th TV. Do I need a 44 switch? Check switch shows 119, 110 and 129 as being all connected and good signals.
