    This is probably a dumb question, but is there a difference in the cable that makes up a component video(red, blue, green) cable and a cable with L/R(red, white) audio and a single Video(yellow). It seems odd that they all have the same specifications except for price. So what I am asking is if a A/V cable can be used for a component cable.

    Thanks,
    Josh

    in the a/v cable, there is no gaurantee that the audio cables in it are 75ohm cables. i think thats really the only difference, other than im guessing the component cables will seem better shielded (whether or not they actually are depends on the cable, but the wires are usually thicker).

    Hi Joshua. Welcome to HTF!

    No, it's not a dumb question. It's actually a source of great confusion.

    Here are the 'rules':

    - A video cable is made with something called "75 ohm" coax. The RCA plug on the end is usually colored yellow to reflect this, except in the case of a component cable set.

    - A audio cable can be made with any of the popular types of coax and connectors: 50, 75, 110, 300.

    (while I am in lecture mode)

    - A coaxial-digital cable must be made with "75 ohm" coax. Yes, the people had a video cable in mind when they came up with the specification.

    - A Composite video cable is a single coaxial cable with RCA plugs on the end.

    - A SVideo is 2 75 ohm cables in a single bundle and a funny 'keyboard' connector on the end and gives roughly a 20% better picture than a composite connection.

    - A Component Video cable is simply 3 identical length composite cables bundled together. It gives roughly a 25% better picture than composite.
