[MPlayer-users] Color problems with video

[Deron Kazmaier]

I've run across several videos that have some serious color problems 
(most notably, skin is shades of blue ie red is blue). Can I correct 
that? The video plays correctly in QuickTime, but it is a group of 
videos from one person that does this. I presume it is some kind of 
confusion as to the color encoding method used in the video. Sadly, I 
don't have a way to test this except with the (beta) decklink driver so 
I'm not entirely sure where the fault is.

Thanks!
