Hello all i have asked this question under other headers but had so many opinions i just want to get the best way then go for it!

What i am looking to do is connect a pw6 wall mounted to a sony dav sa30 and pace sky + box. i have listed the specs for the 2 items below. As i am looking to create a minimalistic look i want to have the sky + and dav sa30 on the opposite wall.. this will involve chasing out the wall below the PW6 then running what ever cable i go for through a 12mm hole in a wall for about 8 meters then back in through another 12mm hole. The reason I am looking to go through the wall is to completley hide the cables cos my chick hates them and this is one of the conditions of being allowed to buy a plasma in the first place as in " think of how much room it will save and no more cables !" oooo rrrr so if you guys can give me one last opinion before i shed out 2k plus cables and converters it would be greatly appriciated.. getting rid of my bird is not an option !

By the PW6 I assume you mean the Panasonic? If so but the component video card for it, buy from Scancom UK one RGB to COmponent converter (90 quid) and put this on the output of the Sony (RGB out) - Feed Sky into Sony RGB. Now pass 3 RCA or BNC type cables to Panny & hey presto! Best resolution from your setup.
