Hi, Im just about to receive my sky+ box and have already bought a JStech RGB>component converter. I assumed that since I am using the optical out, I would need a Scart RGB video only cable to connect to the Jstech. However the manual states that a full RGB+audio cable is required. Does anyone know if this is really neccessary.... Do I need to go get another cable... As always, any help is much appreciated! Regards, Nick.
