I am getting the dreaded message from Directv about not having HD cables every time I access the channel guide and some other functions. I've read the advice on this board and have a couple of questions, not being technically inclined. My setup is a Panasonic 1080p 52" television connected to a Directv box. I have a second set that gets its signal from a Radio Shack a/v signal sender/receiver (the sending unit is connected to the Directv box and the receiver is connected to the second set through the component inputs). The second set is getting the Directv message. I'm wondering if a component to composite adaptor (like the one at Monoprice) would get rid of the message and, if so, how to hook it up. Should it be connected to the Directv receiver and then to the Radio Shack signal sender or to the Radio Shack signal receiver and the second television (or some other way)? Or, if it won't work at all, is there any other solution (other than to change the resolution on the main set every time I watch the auxiliary set)? Thanks very much for any help!
