Slow the video down to half speed if it goes too fast.
I started with a clean Kodi 16.0 Jarvis, you can download from their official site –
Don't hate on me for using 16.0, in my opinion the best layout kodi has ever had, 17.3 is messy and i simply do not like it. Also there is a bugg in 17.3 on Covenant, you can't change the page viewing movies, it will automaticly change back once you go to the next page! You have many more options to change your interface on 16.0
