I have a install for MRV set up for next Friday. I'm wondering how my cabling will be affected as my DVRs are in entertainment centers and such and not easily accessible. If I know what cable runs are changing, I can have this ready to go for the installer. Currently I have 2 HR23s. Both have double strand coax coming out of the wall, connecting to 2 BBCs, and then going into the DVRs. (I do not currently have a SWM dish.) How will this configuration change? In one of the rooms my Internet router is sitting about 5 feet from a DVR, and about 8 feet or so from the coax wallplate. Will the tech have to do any additional wall fishing, or can he use the existing coax runs?
