This is probably an oversight on Plex’s part, but - until they realize it, or users make their case (hasn’t done much in 3 years, has it?) - here’s the work-around:
Plex is looking for a Folder to put recordings into. I happen to only have one TV Show Library (with many folders scattered over 6 HDDs), but I created a Folder so all recordings will go into it and not be scattered to heck and back in with a thousand other shows/movies:
Note: The folder under TV-DVR is TV-Movies - it’s added to a/the Movies Library:
The ‘Folders’ you create - and lead Plex to - can be in any Library you want.
Can’t they?
As soon as you create that folder and add it to a library, it’s going to be a valid target to aim recordings at and as soon as you aim one there (recording options - when you schedule the recording) - it’s the new default.
Aim a Movie recording at your ‘TV-Movies’ folder - it becomes the default for ‘DVR Movies’.
