I currently have the bog standard box only. What i'd (think) i'd like is a quad lnb from the sky dish, with 3 cables all able to run sky plus on them. (ct100?) one cable to go downstairs, and two to go to 2 bedrooms. Whats the limit on what can be run? And, if i purchase these boxed privately, do i have to have any of them connected to the phone line. (assuming im taking multiroom) I think i will end up with one HD unit downstairs , and 2 x sky + boxes upstairs.
