I have a PS2, and a DC, as well as an RGB capable DVD player. All three deviced NEED an RGB capable SCART port (I know I can use a composite signal on the PS2, but it looks like ****). My TV only has one SCART port, which is RGB capable. How do I hook up all three devices? SCART switch boxes (the ones I've seen) only support RGB on one, sometimes two of the OUT-ports.
