I wonder how this would happen.  The 'fullscreen $1' method queries the 
OS for the screen dimensions and sets the window to that.  Maybe the 
dimensions are not returned properly?

Are you using pix_movie or pix_film + pix_texture?  pix_,movie has an 
additional optimization for getting pixels to the card.  It's basically 
CoreVideo as a GEM object.  With frame sizes that big it can make a lot 
of difference.  I was able to get one 1080 stream going 60fps on a 2Ghz 
G5 textured to hundreds of Geos.  There's room for more code 
enhancements for the PPC 970, but I don't even have decent access to 
one for testing!

Does that codec use both CPUs for decompression?  I would think it 
would, but haven't really confirmed it.

Thanks, you too.  Post some documentation of the project online if you
