I've just ran 10m of component cables from my projector to my DVD player up through the ceiling and down a nice channel I've cut into the plasterboard wall. The cables are housed in some trunking from B&Q. My question is how much interference will I cause to my component feed if I run a VGA/DVI cable alongside... and some coax to a Sky box? If it's dependant on the quality of cables can someone advise of the specs required so as to cause as little interference/conflict/whatever as possible? I've saw a few installs on the forums where it looks as though folks are running the full quota of cables to their projectors. Ta.
