I know this is an old thread but just in case anyone picks it up. There's no need to bury the cables in the wall anymore if you don't want to go to all the hassle and expense or just can't because your in a rented house or flat and yer landlord ain't keen on you digging his wall out !!. I saw this cable cover system being demonstrated by a company from Hull at Costco about 3 weeks back. Costco don't sell it yet and I think it's only available off the net.
Anyways I bought one because it looked classy and they claimed it just stuck onto the wall without the need for any screws etc. I was a bit scepitcal about that but there was screw holes fitted just in case and they offered a 14 money back guarrantee, but it fitted just great and looks a million bucks...no more digging the wall out for me when I want to change out a cable 'cos the one on my new games consol is different to the one that's already there......anyway check it out at iconceal.tv
At £45 it's a bit on the pricy side but a damn sight cheaper than getting a leccy in and a plasterer and a painter and decorator:hihi:
