I have an existing set up of Sky+ in one room and Sky in another room. I am keeping my Sky subscription in both rooms and have added a Humax Foxsat HDR to take advantage of HD Freesat transmissions. Sky wanted £199 to upgrade to HD! Can I use 2 Maplin cable switches to split the cables between Foxsat and Sky+ box? I don't necessarily need to be able to record from both boxes simultaneously but want to be able to switch between devices when a HD programme comes on that I want to watch or record. The Sky dish is 3 floors up attached to a chimney and I guess would be expensive to change the LNB to add more cables?
