The value (not the human-readable name) for the setting is opengl, not
OpenGL. With caps, it is equivalent to "-O ThemePainter=qt" or "-O
ThemePainter=xbmc" or "-O ThemePainter=Smith&SonsSpeedyHousePainting".
(I.e. anything that's not "opengl" uses the default, which is the Qt
painter. And, really, even "opengl" uses the Qt painter if the frontend
was not compiled with OpenGL support.)

The -O argument to myth applications is the, "Settings Override,"
argument--meaning, "For /just/ this one execution, ignore the value of
the setting that I configured and stored in my database and use the one
I'm supplying on the command line." So, you just need to fix the
setting in mythfrontend settings under TV Settings|Appearance. If you
can't use OpenGL (and, when you're using VNC, you probably can't use
OpenGL as VNC has no OpenGL--though it might kind of work with
sufficient processor power if using a :0 VNC session), set the Theme
Painter to Qt in settings.
