I looked at your screenshots and used the eyedropper tool in IrfanView to look at your color levels. The YV12 screenshot looks like the correct image to me, on a display properly calibrated for Video levels (as per the NTSC specifications).

In some spots the YV12 screenshot dips below level 16 in one of the colors - 14,20,20. In Overlay this would be clipped to 0,4,4, which would would give you the wrong color (not that you would see it!

). This confirms that the YV12 shot is absolutely correct.

Shadow detail is a little bit crushed in the RGB32 shot - but considering the source, who cares?

I think you need to fiddle with the player's brightness setting - or you can use FFDShow to clip and expand the levels.
