I have cable tv in my living room, but i would like to be able to watch it in my bedroom. is there a way i can do this without having to rent another box?
If you are based in UK, there is a very good one you can get from argos by philips. This has 2 scart connections, so you can also send pictures from a DVD player or VCR without having to disconnect and reconnect said devices.
I use something called a DigiSender. It works perfectly anywhere in the house. Cost about �120 a couple of years ago although I think they are cheaper now.
