I am planning on wall mounting an LG PX11 plasma that has finally arrived at John Lewis ready for my collection. I have already got an RS100 fixed wall mount ready for the job. I am planning on running the cables through the (external wall) along the outside and then back through to the Sky and Xbox. My only problem is that to get a scart socket through the wall I am going to have to drill a hole the size of the Blackwall Tunnel! - Well at least 50mm. Is there any way round this? I don't want to channel the wall out if I can help it as decorating etc has already been done.
