So Plex does keep a long standing record of what you have watched not based strictly on what is in your library.
So, with the “Advanced” Feature of “Delete Episodes After Playing” set to “After a day” if I record an episode that I have watched even a few months ago, Once it is finished recording and processing it will delete the show’s file right away. Seems the “Fix” for this is to not use the “Delete Episodes After Playing” and set it to default of “Never” and then manually delete each show as needed to clear up space on the DVR drive.
I don’t see this as much of a “Fix”, but probably a lot of people are happy with this feature so they don’t catch episodes they have watched before and deleted at some point.
Does anyone know where the file is located that keeps track of what has been watched? I may want to run a script via cron on my server to delete that file and that would be a real “Fix” for me.
