Let me describe it better

Power on Pc and start DSPlayer.
Play Thor Ragnarok ------->Render time 11ms
stop Thor
Play Venom ------------> Render time 11ms
stop Venom
Play Avengers---------> Render time 40ms (First Que to fail is Render)
stop Avengers and exit Dsplayer
Start Dsplayer and play Avengers---------> Render time 11ms
If i choose DXVA2 Native in LAV this is not happening and i can play as many files i want in a row (but with slightly raised times ~17ms). 
I am very happy by using DXVA2 Native but i am under the impression that D3D11 is better.
Regards and Merry Christmas
