Recommended system packages
2012.02 release is recommended. The key components include:
Kernel: Linux 3.2 or later
Libdrm: libdrm 2.4.31
Latest VA API releases
The latest VA API packages recommended for Intel® graphics cards are:
Libva: libva 1.0.15
Libva-driver-intel: libva-driver-intel 1.0.17
In order to use VA-API, you need a media player that supports it. e.g. VLC 1.1.x, MPlayer with VA-API support, and GStreamer with VA-API support.

Known Issues
During stress testing, sometimes mplayer stops at a frame in some streams
Under certain circumstance, very short period of arrtifacts on one frame when playing back some streams
