Start Xorg only (no Xgl), and check whether you have Direct Rendering enabled with glxinfo.
If not, check that you are in the 'video' group, if you're using the default configuration.
This is all good, as also evidenced by: #1 The nvidia splash screen on X session startup #2 glxgears gets 1800 fps instead of the 250 it would get otherwise
However if I say "mplayer -vo x11 dancemonkeyboy.mpg" it plays solidly, whether being dragged around the screen, made transparent, played on the corner between 2 desktops or what have you. -vo x11 tells mplayer to use xshm. It's slow.
Do you have DISPLAYMANAGER_XGL_OPTS in /etc/sysconfig/displaymanager? Did you run SuSEconfig after adding that?
Alternatively, you could also try -vo gl2 or gl
Don't use -vo gl2 or gl under Xgl. It will probably always be slower than Xv, and if Xv doesn't work, OpenGL typically won't as well.
Noted, I was checking alternative output methods to get a good set of data points - your later posting seems to address the issues I'm seeing on the problematic machine - thanks for the info. Joe
