As you suggest running mplayer with -vo x11 displays normal colors, and
-vo xv displays "reversed" colors.  Is it possible to control the video
output method for totem and/or gnome-mplayer?  If so, how?  

I suspect there *is* a bug in the driver, since I've never seen this
problem before.  Maybe it's time to switch back to the free drivers.
I'd like to report the bug, and (as I wrote before) a test file would be
extremely useful for this.

Vlc is available from the rpmfusion repo.  What are its special good
qualities as compared with mplayer and/or totem?

Thanks - jon
