You don't need dri for smpeg to play movies - smpeg, actually, is just
rendering to an SDL surface, which glmovie initialises as an OpenGL
screen, and then just dumps frames to the screen.

You /do/, however, need DRI for most openGL stuff in X4 and above. It
basically provides a faster channel for you to get stuff from userspace
onto a graphics card. [the nvidia drivers don't use it, because they
completely sidetrack the whole issue by skipping the X layers and
shoehorning stuff straight into their kernel driver]
