Hi guys.
I use a mounted cache with rclone and created a script to precache the episode after the currently playing episode in Plex. I found a few scripts that cached On Deck episodes but if you binge watch episodes that is not much use. Hope someone finds it useful...
Python script to cache the next episode of a TV show playing in Plex using rclone (github.com)
