Hi, I am having Sky HD installaed later this month in the lounge. I have a second screen in the kitchen which is currently linked via RF (coaxial). I have the opportunity to chase in some new leads to the kitchen, to allow for the possibility of a small HD screen in future. So the question is: - should I stick with existing RF feed? - or go for SD composite video ? - or HD component ? And also would I notice the difference on a small screen anyway? Thanks!
