I have directv (actualy 2 dishes and 2 4 way multiswitches 1 feeds upstairs and 1 downstairs--its a long story don't ask).

Now I just want a second tv in a room behind the theatre to be able to ge the same satellite programming as the theatre( ie share the receiver) . The theatre has a sony tivo directv receiver and one output feeds the tv directly and the second feeds the stereo tuner for those times I feel like waking the whole house. How can I get the signal to the next room and be able to change the channels from the new room? Is there a wireless way? How do I control the tivo box from the other room? I know there must be a good reliable way to do this.
