Gabucino,

   Do you know if either plugin uses MESA_ycbcr_texture?  this would
avoid the need for you to convert YUV data to RGB in order to render it
as a texture.  Should speed things up of OGL.  when I looked at the
xine plugin source, it did not support this.  For systems that do not
support the extension, you could always fall back to RGB.  As Ian
mentioned, some of the other extensions coming down the pike will also
help performance:  APPLE_client_storage and such...

I've just been looking at the one in Xine, and it just uses plain RGB square textures.
