Hi All - I am new here to posting, but did a lot of reading in the forums before deciding to go with Dish Network. Very pleased with my choice, since in my area the cable service is limited and expensive. I went with the all HD service with Dish since the TV I watch most is HD and felt ripped off with cable paying all that money to only have 10 channels in HD. Now all I pay for is HD channels. I digress. I bought my house in May 08 brand new. The builder was nice enough to wire two rooms for cable (living room and master bedroom). The wires for these rooms come into the basement near the electric box. When I had Dish installed the guy put two sats on the roof and ran cables into the basement. So essentially there was one outside wire coming into the basement (or maybe two, but I think he reverse split it down to one) At which point he took that wire and split it so it connected to the wire going to my bedroom and another to the living room. In the living room he installed a VIP 722. What confuses me is that the 722 should drive the upstairs TV, so I expected a second wire coming out of the 722 going upstairs but what I think he did was take the wire going to the 722, split it and have one coax going into the input and one to the output... and I guess the output can go back down the same coax going into the 722 and back up to the TV upstairs? Anyway, thats the background. I was thinking about replacing my TV upstairs with an HD so I can wall mount a TV in my bedroom. However, I can't stand not having HD service on an HD tv. So I would want to run a 622 in that room and then be able to run a fourth TV later off that. Additionally, I would want to take the output for TV2 from the 722 and run a non-HD tv in another bedroom. So, I know there's a lot going on there, and here is where my question is: To wire the two other bedrooms in my house I can easily drop coax down from the attic through closets and put jacks into interior walls. However, I need to get live coax to these cables in the attic. My idea would be to splice down the wire that goes to the master bedroom (since I have a vaulted master ceiling) and I believe - could be wrong - that the coax for that room is accessible in the attic. But the problem would be that if I splice this line, its essentially the output of the 722. Argh. I suppose if I really wanted to do this, I could call up the installer and just talk it through with him. But I don't have the new TV yet and don't want to bother him with a hypothetical question that goes for 30 minutes. But I've been obsessing about how to do this. Thoughts?
