Hmm... I wonder if anyone is having success with OpenGL?

For me, the slowdown occurs even with simple video fades.
Any time there's any video processing I get very high CPU load and a big
drop in framerate.  

If I just use X11-XV, CPU usage is hardly impacted by fades and simple
plugins.

Its almost as if the OpenGL processing is being done by the system CPU.
