I have had a Q10 pro for a number of years now with no problem. It has a 3TB HDD installed which is nearly full. I removed a number of movies to make space on the HDD. But now, when playing movies, about half way through the movie it will begin to stutter. I have even gone and played movies that previously played fine, but now will stutter. What could the problem be? and is there a fix for this? Movies are all played through Kodi.
