I am a little late reading the list but I see you found out that there
are three DVI specs and only 2 of them support analog and almost
everyone is the third.

I have a fairly high end consumer VGA to S-Video converter and it is
crap.  Seems like it should be easy to do but I must be missing
something.  VGA is just the three colors plus horizontal and vertical
sync.  Component just adds the sync signals to two of the color
signals.  S-Video is more complex so perhaps it is possible to find a
cheap VGA -> component converter.  I see that there are converters in
the $ 60 range but I have no knowledge if they are any good.  Perhaps
someone else on the list does.
