Change how plex sees end of movie

[tom80H]

There’s currently no means to set your own threshold or disable this behavior.
However, there’s a feature suggestion addressing this (though it got little attention/support so far):

[Feature] Provide a way to resume near the end of a video

There needs to be a way to resume a video when leaving off near the end (or even near the beginning). A simple idiom would be that if the user pauses the video before pressing back or stop that it always saves the resume position, no matter how near the end the video is. If the user exits the video without pausing, then then normal “you’re near the end so we’ll mark it as watched” algorithm kicks in.
