Yes ... OpenGL vsync is enabled.
nVidia - I just installed in the last couple of days so I pulled the
latest from the nVidia website. It appears to be 8178.
Are there utilities I can use to make sure OpenGL and Xvmc are installed
and operating properly?

Are you running with OpenGL Vsync enabled? Also, what version of the
Nvidia drivers are you using. I myself have found, and have others,
that 7676 seems to work the best of the recent driver releases for XvMC.
