You are using a proprietary driver from NVidia, so you will get better answers 
at nvidia's forums. Since you are using xine, give a try on the OpenGL outputs 
(or try a different player, VLC or MPlayer). NVidia also ships with good 
documentation, you might want to check it out, shoud be around 
/usr/share/docs/NVIDIA something.
