Ultra Slow video playback!!!!

Hello
I have downloaded Kodi 17 at my bohdi 4.0.0 Linux laptop. But i have a big problem. Kodi plays videos stored in the laptop’s local storage ultra slow. A black screen shows up, only with the cursor and the video does not play.
https://drive.google.com/file/d/0BzYxwDi…p=drivesdk I recorded this with my phone, cause probably you don’t understand what i wrote.
I haven’t change any settings.
Can anyone help me
Thanks
