I have the 922 in the family room with the big tv, and an old 4x3 set in the bedroom. If I want to watch tv in the bedroom, and now use the 922 to send the signal when in dual mode, will it only come up to the tv in standard size regardless of the signal being in hd, or will a hd show come to the upstairs tv in hd? And if I want to do this, what kind of cable is used, and where do you plug it in on the back of the 922 to send the signal upstairs? And, will this allow me to watch recorded shows on the bedroom tv?
