I ran the test X.  I'd try it on a console window, but I don't want to do that
until tomorrow because I'm seeding a bittorrent and I don't want to kill it 
until tomorrow.

Test 1 runs fine: I see the green square.  Then test 2 says it is starting,
saying I should see a mosaic pattern.  I do not see the mosaid pattern: instead
I see a color blend.  When test 3 starts, saying I should see a color blend,
I continue to see the color blend; the display does not change.  In other words,
in my case, the results of test 2 are exactly the same as the results of test 3.

I did try it and unfortunatly it did not work for me.  (In X), when I use -vo xmga, 
the picture I see isn't viewable: there's a lot of horizontal lines across the
window.  Without -vo xmga, using whatever mplayer defaults to, the picture is very
good quality.  Makes me wonder why I wan to get xmga to work at all :-)

My card is a G200 AGP, not a PCI; I don't know if that matters.

Thank you kindly for your suggestions.  Any additional help would be greatly
appreciated.
