I’m adding DS9 special features to Plex, in the Specials folder. I checked TheTVDB and saw that only 2 specials are listed, so I started at S00E100 so there wouldn’t be a conflict, planning to name them manually.
When I added the first batch of files, I saw that Plex is pulling metadata that correlates with season 6 and 7 DVD special features (which are not the ones I was adding, so it’s not pulling this data from the filenames).
I checked and verified that TheTVDB is listed as the agent for this library.
Here’s a screen shot of what I’m seeing. As an example, my filename for episode 100 is “Star Trek Deep Space Nine\Specials\Star Trek Deep Space Nine - s00e100 - Deep Space Nine ~ A Bold Beginning.mkv”.
Any ideas as to where this metadata is coming from?
It appears your Agent for DS9 is TMDB:
Fix Match back to TVDB - or… start at 200…
(see who has the best cast info and stuff and use that one)
(or see if your specials are among those 114 and adjust as necessary)
In addition to @JuiceWSA’s suggestions, you may want to see if you have The Movie Database selected as a metadata source in your TheTVDB agent config as well:
However, I’m not sure how much that would affect what you’re seeing. But it’s probably worth checking as it does appear the metadata is being pulled from TMDB.
It doesn’t - 'cause I do.
In both of those I have the primary agent on top and ‘the other’ one under it
both activated. <—and LMA tattooed as close to rock bottom as possible - but activated - in case I want to use an MP4 file at some point.
I used to think having both of them active helped, but now I’m just not sure if it’s that or Filebot that gives me 99.9985789% success… tis a mystery…
I do know I don’t get TMDB data - unless I abandon TVDB on the spot - and I’m doing that more than ‘occasionally’ these days.
I just tested here, both with TMDB disabled and enabled for TheTVDB agent. With TMDB disabled, it detected as s00e100 generically, with no metadata. However, with TMDB enabled, it detected it as the OP describes (ignore the thumbnail, I used a re-named Jellyfish sample for the test):
So, it will pull the episode info from TMDB if you have it enabled as a source for TheTVDB agent.
For comparison, here’s how it detects with TMDB disabled:
I stand corrected.
But it’s selective 'cause I never get actor images to jump the gap, but perhaps that along with Filebot accounts for my insane success rates.
I simply don’t have to Fix Match - it’s as rare as a Total Solar Eclipse.
Thanks, gang! I do indeed have The MovieDB as an additional agent under my TVDB agents settings.
I guess I’ll have to start my numbering higher, because (a) I don’t want ALL my TV shows using TheMovieDB, just this one, and (b) I don’t see a way to make this one alone use it exclusively, but © the two databases conflict, because episodes 1 and 2 are using the TVDB entries and the rest use MovieDB. Meaning I have 2 specials that will be left out.
Which isn’t major, but this whole thing is weird.
Update: there is a way to override the agent for an individual show, by using Fix Match…
This did the trick for me. And was worth doing, for the nice orderly preview images.
