I’m exactly where you are on this @Canons900 and I’m looking for simplicity too. Just because our cord-cutting journey needed to have full family buy in I went the route of having Plex as our main UI so we have a single UI for movies, TV shows, etc, with Tablo doing all of the recording and Tablo Ripper getting all of it over to the NAS Plex is configured to use.
As you said, my dream as well is Plex someday supporting Tablo tuners. It would remove a couple of possible “failure points” and Plex does have some features that are useful for our household (easy offline sync for trips, etc.). Doesn’t hurt that we have a lifetime Plex Pass already.
