The episode metadata for DVR recordings initially comes from the EPG provider (if you’re using Plex’s guide data). If the descriptions were incorrect immediately after recording, that was the source of the issue.
When you performed the Plex Dance on the series, that should have rematched it using whatever agent you have assigned to the library to which you are recording. Normally, that will be the Plex TV Series scanner/agent now.
Questions:
- Did you perform the dance on the entire series, or just a particular episode (or season)?
- What agent and scanner do you have assigned to the containing library?
- What is the series in question? Do the episodes’ descriptions appear correctly on TVDB and/or TMDB?
I’m not necessarily suggesting the Plex Dance by the way. I’d just assumed it was already done based on prior comments. Doing so has implications for future matching and recording, if the EPG data and the metadata sites don’t agree on episode ordering, for example.
