Let me start by saying I know that quality of cables are different, but that is not my question. My question has to do with the signal running through the cables. For instance, if I have standard a/v cables are they constructed for their specific purpose (yellow for video, red & white for audio) or are the cables colored just for the consumers sake? Or if you don't understand that... Is the yellow tipped video cable constructed differently than the other two cables? Just curious.
