Which exactly?

Probably your drivers do not support the GL_ARB_pixel_buffer_object
extension. Your old MPlayer version maybe didn't print that message
because support for this extension is quite new - in this case MPlayer
should not be any slower that before.

-nodr if that message annoys you (should not change anything else).
-vo gl:yuv=2 or -vo gl:yuv=5 might give a speed boost.
If there are bugs in the vsync handling of your drivers, or the framerate of
your video is above the refresh rate of your screen, try -vo gl:swapinterval=0.
Otherwise, refer to the man page for details and more options.
