Are you missing entire providers of just individual shows/movies?
Plex is using data from an external source, so they depend on that source being accurate.
As for your own recordings… if your library is using the current-generation Plex agents, those should actually already show in the Where to Watch hub.
There’s an existing suggestion to display if a show or movie are listed on the live tv guide(e.g. as a to-be recorded option).
