    What's the difference, if any, in these cables? If you took good old AR video/left&right audio cables and used them to hook up a DVD player to a TV via the component red/blue/green connections would it work?

    Regarding a/v patch cable, (L+R+Vid) it would work but is not ideal as two of the cables would have the wrong impedance. If you were to look closely you may see some artifacts (like ghosting, bleeding for instance).

    The component cable is 3 composite video cables.

    Here are the rules, and generalities:

    All Video cables must be made with something called "75 ohm coax". This is so the cable matches the input electronics on your television.

    Audio cables can be made with any of the common types of coax with 50 ohms being the most common.

    SOMETIMES: the Left/Right/Video bundles are all made with 75 ohm coax and can be used as 'less-expensive' component cables. But places like Radio Shack caught onto this and now make their bundles with different audio coax. (I dont know what AR does).

    And NO, you cannot tell the impedence of a cable just by looking at it.

    It wont do any damage to try the hookup. If the video image looks good, you got lucky.

    But you do know that decent retail component cables are about $29-$39, and high-def rated video cables start at about $49 from the custom cable sites?

    (Yes, high-def rated cables look identical to component cables - but like roads, they are designed to handle different speeds. If the package says "Component" - the cables were only made compatible with the 1940's component video standard.)
