The Overlay code was not written to handle YV12 very well, which is the
colorspace you are using with DVDs.  In YV12 you have three planes: y, u
and v.  The latter two contain the color information, but are reduced in
size and this means you can't change the color of a single pixel, which
makes it complicated.  Because of this for YV12 mplayer only sets the
Luminance (Y), so the subtitles are kinda gray with a bit of the
original color shining through.
