mate i used to have my house wired up like you want. i used the rca outputs of the sat box connected to an rf converter, and conected to that was the aerial cable going to the bedroom. Problem was you had to watch the same channel that was on in the living room and you couldnt change the channel. Now I have a dongle called an 'Android Mini Pc', with the 'timote' app downloaded on it, and you plug it into the hdmi port on the second tv, you can watch a different channel to that shown in the living room and you can change the channels from your bedroom. all this without wires as it sends the signal through wifi, all you need is the openwebif plugin on your zgemma. the android mini pc bascially turns your tv into an android tablet, so of course watching tv isnt the only thing you can do with it. It only costs around £26 on ebay but you need the remote to go with it which costs another £11, (you could always buy a mouse to go with it, but in my opionion the remote is best) you can download that app onto your smartphone as well (iv used the vu+ app as well to do the same thing but i think timote is better)
