Those references don't support your position.

From that page: "...it reduces things like color bleeding and dot crawl and
greatly increases the general clarity and sharpness of the picture. ... The
increase in picture quality that you'll get in platform games (like the PS2)
when you move from composite (yellow-plug) to S-Video is very noticeable and
is well worth spending the extra money to buy the optional cable. "

Yes, the resolution is the same, but that doesn't make the quality the same.
After all component video is the same resolution as well.

That's simply out of context. The full quote was "S-Video is sometimes
considered a type of component video signal; however, it is also the poorest
quality-wise, being far surpassed by the more complex component video
schemes".
They were comparing S-Video to other component signals, not to composite. In
fact the previous sentence in that article is the relevant one: "This means
that S-Video leaves more information from the original video intact; thus,
it offers an improved image reproduction compared to composite video."
Here's another reference:
http://www.michaeldvd.com.au/Articles/VideoConnectors/VideoConnectors.asp
"In a nutshell, if your display device can support it, a component or RGB
video connection will give you the best possible image from DVD. An S-Video
connection is not far behind in quality. A composite connection, however,
will result in a perfectly acceptable, but less than optimal result from
your DVD player."
My TV's manual agrees:
"DVI-D, D-Sub, Full SCART > Component > S-Video > Composite, Half SCART"
Though I found the difference between DVD-D and "D-Sub" (VGA RGB) quite
noticeable on that TV. On my LCD monitor DVI-D and VGA RGB are
indistinguishable.
In my limited testing of the two formats I could not see a difference.
You may have had a poor source or a very good composite connection.
Typically the difference is glaringly obvious, especially on computer
outputs. Even if the difference was insignificant with video it's likely to
be obvious in the MythTV menus.
The specs do not speak of vast improvements either.
Yes, they do. The separation of chrominance from luminance is a vast
improvement. Note that it's also the difference between composite and
component (in it's usual TV use YPrPb incarnation).
Cheers,
