I'm a new Directv customer, just scheduled the install. I've never had satellite before but had a question: I have a 5 yr old home. I understand the installer will have to determine if the current cable lines can be used for satellite. It has to be RG 6 I believe. I'm having whole house dvr installed in two rooms with a dvr in each room. I'm keeping my broadband internet connection. Assuming the current cable lines can be used by the installer, my plan is to keep the cable modem and router hooked up in the office and have the dvr's in the master bedroom and the family room. Is this even possible? or will the installer have to run separate lines b/c of the cable modem?
