737-29894: Radeon HD 2xxx AGP Series - High CPU usage or system crash during HD playback

Symptoms:
On AGP versions of the above mentioned graphics cards the Hardware Acceleration does not get enabled. High CPU usage, stuttering HD playback or even system crash are expected behaviours, although DXVA (DirectX Video Acceleration) is enabled by the application.

Solution:
The root cause of the problem has been identified and a resolution will be available soon. The Catalyst 7.12 is the anticipated driver version to resolve this issue.
