I think you won't need mplayer. The test programm calls the directx
functions themselves. It doesn't create a window, though.
Btw. what about the  NV_PVIDEO_LUMINANCE and NV_PVIDEO_CHROMINANCE
registers? Do they change?

you can do this with
fwrite(info->video_base,info->chip.fbsize,1,fp);
Btw. you can find nv10 registers in
http://rivatv.sourceforge.net/stuff/rules.tar.gz
