And that ticket is bogus, because comparison is made between 4:2:0 and 
4:4:4. And when the reporter says the colors are muddy, he means the pixel 
format diffrerence, not the color space difference. So there is nothing to 
fix regarding the color space, because that is OK, and the different tone 
of green around the edges are only because of the 4:2:0, not because 
the wrong colorspace is used.

Marton
