25 is a more than I have gotten running so far - maybe PAL is more efficent
than NTSC.  The reason pix_movie is so much faster is that it uses the most
efficient texturing path by default.  The standard pix_texture code waits
for the texture upload to the GPU before continuing which stalls all of the
rendering.  You can send a 'client_storage 1' message to pix_texture to try
and get that object to use the more efficient code but it doesn't always
work - especially on the MacPro with ATI.
