I didn't get that impression but I have asked the questions of The OP.
I think surface mounted trunking is uglier than a power cable hanging down and chasing the wall and fitting a new socket using a spur, T&E etc. is a heck of a lot of work even if the OP was competent enough.
After all, I assume the other wires will come out of the TV and go down to the media unit for their connections.
Anyhoo.....no arguments from me here...need to wait and see precisely what the OP wants..
