i am not quite sure why one would put component on a standard tv. it is interlaced, and you won't get a progressive picture out of it. so the best you can hope for is 480i.
i have a standard 27" with component in, and i can't tell the difference between S-video and the component. if i try to switch the output of the dvd player (which is using the component cables) to 480p, it will not display on the tv.
you can, however tell the difference between s-video/component and the standard rca jacks (like scot said). on my gambecube, when i used the s-video, the picture was clearer and more defined, then with the rca jacks, but it still was not a highdef or progressive/non-interlaced picture, because it was on a standard tv. like the other guys said, you need a HD tv to display 480p and higher resolutions.
