Apologies for what is undoubtedly a very naive question. I'm going to start using the component inputs on my XDE for the first time (currently only use the HDMI and Scart connectors). Can anyone explain: 1. Ignoring brands/build quality, are all component leads of the same type? 2. Do the leads carry sound? If not what additional cables do I need for this? I have no surround sound/amp setup, just the Pioneer plasma speakers attached and wired to the screen. Many thanks for any help.
