We have just had the V6 box from Virgin Media. We have started going through the instructions and found that the box needs to be close to the TV for the HDMI lead, but also close to the Broadband Router for the coax connection. We have had the coax connection installed into our hallway last year but for it to be nearer the TV we will need to reroute the cable into the living room. How do I book an engineer to do this job? Will the previously drilled hole be plugged?
