Your G3 doesn't support non-rectangular textures, so QE is disabled  
and CoreVideo fails silently. I remember now that vo_macosx just  
displayed black for me on one of those; I guess it should be  
detecting http://oss.sgi.com/projects/ogl-sample/registry/ARB/ 
texture_rectangle.txt.

And yeah, it looks like HD video makes an unnaturally big difference.  
I'm not good enough to touch swscale, which is right below the memcpy  
in Shark, but prefetch hints or something might help there.
