has started on an OpenGL video renderer which should allow us to implement some
really slick deinterlacers in hardware. But this isn't very far along yet and
we will not be writing an XvMC replacement in OpenGL fragment programs anytime
soon; we may eventually do this since it doesn't look like nVidia will be
adding MPEG-4 AVC support to XvMC...<o:p></o:p></span></font></i></p>
