Sorry if this may have been covered.... Is it possible to switch two sources independently to two screens i.e. PS3 & SKY HD fed to two screens with the option to use PS3 in one room and SKY in another at the same time and vica versa. I'm aware you can buy a 2/3/4 input with 2 output switch, but then the source would have to be watched in both rooms !!!! Any help would be appreciated, cheers.
