    I've heard that audio and video cables aren't the same, that they differ in impedance. What are the main differences between the two? Can video cable be used for audio connections and vice versa? Also, I think I remember reading somewhere that video and digital coaxial cable are the same thing. Is this true?

    Audio cables are 50 ohm, video cables are 75 ohm. Audio cables cannot be used as video cables because they can cause ghosting of the picture due to reflections in the cable. Video and digital (coax) cables are interchangable because they are both 75 ohm.
