Vulcan is correct in that the yellow cord is usually thicker than the white/red cords, and meant for audio. Here's the reason: a video signal generally requires a different (higher) "resistance" within the cable for optimal transmission in comparison to an audio signal. This means a video signal also usually requires more insulation from surrounding electrical noise and artifacts to achieve a clear picture -- moreso as the length of cable increases -- than an audio cable does to achieve clear sound reproduction over the same length. Though in most cases the type of cable and thickness of insulation is sufficient for the average joe to interchange colours and types without a problem, it is possible for signal degradation to lead to reduced output quality, or lost signal data, etc, in some setup scenarios.
Higher resistance seems counter-intuitive, wouldn't it be lower resistance? I could be wrong though... wouldn't be the first time. If you used a cable made out of the same material but with a larger cross-section, the resistance would be lower which would make sense to me.

BTW, to actually add something beneficial I am using leftover component video cables to run 5.1 analog from my Blu-ray to my receiver with no problem. In my view the bigger the pipe the better. I've got a half-dozen of those red/white/yellow cables lying around, but the gauge of the wire is so much smaller I figure I'm better off using the nice big fat component video cables.
