Hi,

I have recorded a short HDTV (H.264) video within MediaPortal. Now if I play this video in PDVD8, DXVA is active (CPU load 5% or less). If I play the same video in MP, DXVA is inactive (CPU load 60..80%).

I have enabled DXVA in MP configuration, as well as in PDVD8 and in CCC, but it seems that MP doesn't turn on DXVA. How come?

Can someone help?
