Why do some TV episodes have wrong data?

Trying to get all my American Experience documentaries on my Plex server. However, I have run into a frustrating problem. Plex (or the data bases it uses) keeps getting a lot of the episodes data mixed up and incorrectly applied. Just one example:

Episode name according to IMDB and PBS: American Experience - s08e08 - The Wright Stuff.mkv
Plex names it: Spy In The Sky

It even uses the Spy in the Sky poster.
The two episodes, “The Wright Stuff” and “Spy in the Sky” are in season 8 of American Experience. They’re even right next to each other in the order. (Spy in the Sky is actually episode 9.) But, as I say, wrong data.

And, this is just one incident. This occurs also with several other episodes, and I only have about 15 videos.

Another example:

Episode name according to IMDB and PBS: American Experience - s5e11- Seabiscuit
Plex names it: Bataan Rescue

I understand I can correct this in the details of each episode, but as I’ve had to move files from time to time, when Plex scans everything again, they come up with the wrong names again. I would prefer not to have to keep “fixing” the data.

Has anyone had experience with setting up the databases which name TV episodes? Is there one that works better than another? And, if so, how do you change them?

Plex’ default source for tv shows is TheTVDB.com
Your best shot is to get the the episodes in line with their listing sequence…
https://www.thetvdb.com/?tab=series&id=71638&lid=7

alternatively you can check if the show is listed differently in The Movie Database. However it’s in sync with TheTVDB.com in this case.
https://www.themoviedb.org/tv/1181-american-experience

I’ve just double-checked the episodes you listed in IMDB.com. It seems there’s some hiccup as IMDB lists one extra episode (s8e5, aired on January 15, 1996 “Freedom of My Mind”) that’s not in the other databases which results in the other episodes to be one off. The other databases list that particular episode as s7e8.

The easy way… go with the TheTVDB.com sequence.
The tougher way… check out their forums to figure why this is (especially considering your point that PBS’ listing is similar to that of IMDB)

Thanks, Tom. That did the trick. I can definitely live with that method.
