I'm looking to buy a Toshiba TV with component input so will use the component out on my GX7. To do so will mean I have to turn the RGB scart off and component on. My Sky+ box currently runs through my GX7 (to use the RGB in). Will the RGB pass through the Sky+ box and exit through the component outputs and will auto switching still operate. OR do I have to select component out every time I want to watch a DVD and use RGB for Sky+ passthrough????
