Can I connect my Digibox to an AV8 using a scart to 3 phono's to take the RGB signal through the component inputs. The output will go through component to my projector. Or should I use a RGB/component converter. I am trying to keep the cabling to a minimum. I also have an elderly Pioneer 515 laser disc which I would like to connect the same way. The Pioneer was my first bit of kit and it would be a shame to part with it.
