I have both, Kodi 17 (amazon fire tv and amazon fire tv stick) and Kodi 16 (openelec). I also have a Windows 10 server on which nothing runs, not even antivirus. I have shared two folders (movies and series), which I can access adding it to Kodi.
I have all 4 machines connected together through a Google Onhub.
Now, I have only 1080p and 720p movies, but, no matter what, they buffer a lot.
That is driving me crazy. Any ideas PLEASE?
UPDATING: PLEX works perfectly.
