How should I connect my fairly old NTL cable box, made by Samsung, SMT-2100C, to my Onkyo 705. Prior to having the new amp, it was connected to the tv via scart. It lacks outputs having only rf or scart. Can I get a Scart to some other set of cables, possibly component, the user menu offer either RGB or Component out. I want to maximise sound and picture quality. This will be a temporary fix as I get around to a V+ box for the system
