Thinking of getting 2nd Sky+ Box. Having trouble working out how to connect it to a Panasonic plasma 4 without using SVID via Yami A5. Would rather go RGB MAYBE using the pass through on Sky+ box but not sure how the switching would between both Sky+ boxes. Current mirror sub is a Sony Sky box connected Svid via Yami A5. Current Sky + is connected RGB through JSTech RGB-VGA converter DVD Pioneer 525 (getting old) through JSTech RGB-VGA converter. SVHS connected Svid via Yami A5 help?
