Yeah.  Been there.  Check out your xorg.conf.  You probably have glx
loaded in the modules section, and nvidia as the driver in the device
section.  If your system is like mine, then they are grumping at one
another.  Changing "nvidia" back to "nv" [contrary to Jarod's
instructions] will let you use your MythBox.  No doubt this is a mortal
sin, but I haven't been able to find the True Cause yet.  Whats weird is
that I didn't have this problem in 0.17, 0.18 or 0.18.1.
