Ok ... here's my unofficial guide to TV link - forgive me if its sucking eggs ...
TV Link plugs into the RF in connector at the back of a television and uses the aerial cable to transmit remote control signals back to the Sky digibox. TV Link cannot be used with a scart connector or directly connected into the back of the Sky digibox.
You must connect the aerial cable to the
powered RF out on the Sky digibox (I believe that there are two RF outs on the Sky digibox). Also connecting various aerial cables around the house can cause problems with TV Link (something about isolation or crossing wires - can't remember - but if your TV Link isn't working this could be the reason).
So in answer to G1OSE's question ... yes
Take an aerial cable out of the back of the powered RF out of the Sky digibox, wire it to the two other TV sets (using a cable splitter - try
google) and plug a TV Link into RF in on the back of the TV sets. Then when you switch Sky channel in any room it will change the channel on the Sky digibox and therefore all the TVs connected to it.
If you want separate channels on separate TVs then you need to contact Sky and get their multi-room service (this uses the satelite cable to Sky digiboxes at each TV).
