It doesn't need the separate texturing object pix_texture like 
pix_film/video because all of the movie playing and texturing code is 
contained in one object.  On OSX this is an advantage since certain 
fast path texturing functions require tight control over execution 
order that can't be assured when using pix_film+texture.  On DV/SD 
material the difference is only a few percent per source, but on HD 
(1080 in particular) the gain can be 25% or more per source.  I have 
plans to work on a pixel format auto-detection for pix_movie that will 
help make sure the optimum path is used no matter what.
