If you try (R,B) swapping correction, but somehow tones of orange look 
too yellow and tones of cyan look too blue, the problem was actually a 
(U,V) swapping problem. (I mentioned this in gem-dev archives)

Besides, with recent versions of GridFlow, USB cams don't have to be 
handled as YUV and the default conversion is to RGB, and it's much faster 
than in version 0.8.4.
