I just signed up for 1 HD-Dvr & 3 standard. I want all the coax ran through from the dish into the attic and then down through the walls. I know usually they will charge extra for this so I was thinking since I have spool of rg-6 I could run from where the recievers will be, up the walls and into the attic to where they will be ready to hook up to the mult-switch. I dont know if I should run the coax for the hd-dvr because I think it requires 2 lines and if it does maybe the installer will have a coax with the 2-in-1 wire(coax). I am hoping to get the new HR-20 reciever, what are my chances of that and does running the coax sound like a good idea? thanks!
