If I change the episode ordering to use TheTVDB (DVD) I lose all the metadata like Episode name, date aired, etc. If I use TheTVDB (Aired) then I get the metadata just fine.
Let me know if you need any other info. Thanks.
Can you give an example of a show this is happening with ?
Sure, I should have included one in the OP. Gilligan’s Island is the one in this particular case.
You asking the question made me think of something that I hadn’t considered earlier; does TheTVDB have the DVD order list for this series? I just checked and it does NOT which now makes sense as to why no metadata was available.
I know they have a DVD order list for The Dick Van Dyke Show and I confirmed that PLEX is using the list if it’s provided.
I should have checked TheTVDB but I assumed they had all that content set up for DVD as well as aired. My mistake. Maybe this will help someone else who may run into this.
Great minds 
That was exactly what I was going to check. Glad you got it explained.
