Here's my mythfrontend --version

Library API version: 0.19.20060121-2
Source code version: Unknown
Options compiled in:
 linux release using_xvmcw using_v4l using_oss using_alsa using_ivtv using_firewire 
using_lirc using_x11 using_xv using_dvdnav using_xrandr using_xvmc using_xvmc_vld 
using_opengl_vsync using_frontend using_backend

Something I just thought of... What user are you using for Myth?  If you're logging 
in as a regular user (ie. user mythtv), you may want to make sure that this user also
belongs to the "video" group.  At least that's how it is for me.  As well, you may want 
to check permissions on /dev/nvidia* to ensure you have rw permissions.
