How do you connect sky plus to another room?

Have you tried "THE VIDEO SENDERS?"

You get two senders, one a transmitter and the other a receiver.

All you do is connect the transmitter to the tv with sky on it to the scart socket.Switch it on and go into the other room and plug in the receiver sender box to the tv you want to watch sky on.Then you should see the sky picture automatically on the second tv.Personally I havn't used one but that is what it does.Two video boxes one transmits and the other receives the transmitted picture. You don't need cables or wires to connect.
