Hi
I got at big problem, I hav joust upgradet to PowerDVD 13 and love it, but when I playback specíaly MKV files, there i very often, that not all of the screen is updated, there is some big Black fields or flicker on the screen.
I did not have this problem in PowerDVD 12, with the same configuration.
I am playing on an Asrock 100HT-BD i3 with Windows 8 64bit, Intel hd Graphics, ssd disk and 1GB Ethernet.
There is not anything else installed on the computer, than Windows and powerdvd and to completly sure, i have joust reinstalled the computer, so that every trace of other software is gone..
On my desktop computer, have i installed VLC player, and it playes also without problems.

I have given up, i have not any idear anymore, hope that someone can help?

Thanks on advance
