I'm looking to set up a tv to recieve the SD tuner on my VIP 622. I currently have two VIP622 recievers set up with triplexers to run a single line back into the wall. Each coax from the recievers is then set up to run into a diplexer with an output to a DPP44. Then, I have a line running from the DPP44 to my second TV that recieves the SD tuner signal from one VIP 622. However, I can only pick up the Analog signal from the one VIP 622 on that TV. The other VIP622 is on and set up to broadcast on a different channel, but the TV won't pick it up. Anyways, I need to set up a new TV to recieve the SD tuner signal from the second VIP622. I was just wondering what combination of splitters/combiners/diplexers I would need to hook up to accomplish this. Thanks for any help!
