Weve got a Sky HD cable into one part of the property . We want to watch the TV exclusively in another room which has a single cable. If we ask Sky to change this single cable to HD (but leave the original HD cable for possible future use if plans change) firstly has anyone any idea how much Sky charge seeing as how it wont be part of a new installation package, and secondly - if you DID have two or three TV's (all plugged into phone line) I know youd be paying multi-room on top of one HD charge, but is that it, or would Sky charge an HD monthly charge for each TV you had plugged in on an HD cable ? Come to that , is multiroom an extra monthly charge for EACH extra tv as well or is it just the one monthly charge BECAUSE you have multiple tv's? Sorry if thats a bit garbled , but hopefully it will make enough sense to anyone likely to know the answer.
