Is this a limitation of the G200 or of the directfb driver? I'm using onther
program (mga_tv) which uses the mga_vid driver. I also had problems with the
colors there, but then I switched the mga_vid into MGA_VID_FORMAT_UYVY mode
and it works. (The strange thing is that there the v4l is set to
VIDEO_PALETTE_YUV422. When I set it to VIDEO_PALETTE_UYVY then the color is
also bad.)
