If I look at your message, I assume that your onboard video card is ATI.
The solution I presented works with CUDA, which is not supported by ATI. On the other hand, there is no much difference with DXVA in HW acceleration.
For ATI the previous suggestions are indeed valid. PowerDVD checks for HDCP compliance. PowerDVD also decides what videocards and drivers are acceptable. Update to the latest Catalyst drivers to see if this resolves the problem.

What you equally could try, to pump the speed a bit up in case of MKV, is to replace the PowerDVD codec with a CoreAVC codec. This can be v1.8.5 (with DXVA) or v1.9.5, but in your case with CUDA disabled, for x264 coded movies.
In my configuration I use the PowerDVD Codec for the MPEG-2 rendering (DVD/Blu-Ray/HDDVD) and the CoreAVC for the H.264 rendering. THe CoreAVC is currently the best codec for that kind of rendering.
