If you have access to the PlexDVR, would you be able to use the HDHomerun DVR software and use that to record, process through MCEBuddy and then plop into your Plex folder using the renaming formulas?
That’s what I do, and it’s pretty automatic for 99% of the shows. The ones I do have issues with are related to the guide data, so MCEBuddy can’t really fix that. The downside is that you need to use the HDHR DVR app to schedule, and I don’t know how different/better/worse it is compared to PlexDVR.
I’m still working on a workflow that can take a standalone text/json/xml/csv/properties file and run it through MCEBuddy and have MCEBuddy replace the existing metadata with whatever overrides are in the standalone file. I need that for recordings of mostly PBS and older syndicated shows (e.g. Emeril Live! on DABL, Dust on TBD) that don’t have guide data (PBS shows notoriously don’t get episode details/metadata from the producers/distributors like CPB and APM and brand/self/locally produced/distributed shows that sell direct like America’s Test Kitchen or Jamie (Oliver)'s 15 Minute Meals).
