Before i spend any money on a hunch, can anyone confirm whether, if I connect a video sender to mon B on my mux, that I can view the picures on another TV wireslessly?

... and not forgetting that anyone else using a receiver on the same frequency, within range, can also probably display the pictures on their set

and you get a video sender that accepts composite input, and its within range, and its not conflicting with any other equipment you have, then should be ok.

I had a wireless sender that operated at the same frequency as our BT wireless router, tried all 4 channels on the sender/receiver but still got bad interference from the wireless network all the time....
