 I'm using a playback profile with filters, OSD fading and deinterlacing
 disabled, avsync2 enabled and mythavtest for playback (on a 1920x1080 at 50

 With VAAPI video and audio looks OK (although with -v playback you can see
 frames being dropped), intel_gpu_top shows 90-98%
 With VAAPI2 only a few video frames are shown every few seconds,
 intel_gpu_top shows low gpu utilization.
