Bug detailed description:
when use the mplayer to play an media file with vaapi acceleration, the color of  subpicture is wrong. The reson is that the latest mplayer(2010-11-15) has enabled IA44/AI44 subpicture formats but SNB has not implemented IA44/AI44.

Reproduce steps:
mplayer -vo vaapi -va vaapi mediafile
then use left or wrght button to seek.

Currently mplayer-vaapi-latest-FULL.tar.bz2 in
is the version of 2010-07-13 which has disabled IA44/AI44. But in the version of 2010-11-15, it has enabled IA44/AI44.
