I am trying to hook up two TV's to one Joey and the cable I have is a Component with the red, green blue plugs. One tv is hooked with HDMI. The back of Joey only has red, white and yellow ports, is it possible to hook the other tv with the red, green, blue plugs? I have it hooked up now but the picture is black and white. Or do I need to just go buy a Composite cord? Or is there an adapter that would plug into the back of Joey to change red, white, yellow to red, green blue?
