Sounds about right, I can't imagine that any integrated
GeForce could handle the OpenGL renderer. You need a fairly
beefy card even for NTSC/PAL, especially if you use any
of the OpenGL filters.

Ok, just point them out to me.

It looks like you are linked to the Xorg libGL but I presume are using
the nVidia proprietary driver. You must use libraries that match your
drivers, otherwise segfaults and kernel lockups are sure to follow.
