This will not work properly when theres a mismatch between tvdb and tmdb right? Thats why our original plan was to wait till tvdb pr is merged until this feature.

Unless you have some other ideas? (Haven't gone through the code yet)

You’re absolutely right about the TVDB/TMDB mismatch concern - I considered that during implementation. Instead of relying on direct TMDB ID mapping, I leveraged the existing Sonarr connection via externalServiceId and match episodes based on season and episode numbers. This approach works well for the majority of shows where episode numbering aligns across databases.

That said, I recognize there will be edge cases where TVDB and TMDB have inconsistent episode structures. I saw this as a pragmatic first step that covers most use cases.

I thought about a few options moving forward:
• Merge this as-is to support the majority of shows now.
• Hold off until the TVDB PR lands to enable more precise mapping.
• Make this behavior optional until we have more robust TVDB integration.

Wdyt ?

Hold off until the TVDB PR lands to enable more precise mapping.

I think this would be the better idea. Or it will cause an influx of support requests saying why is this episode not available when it is etc etc

Can a preview be made for this PR when the merge conflicts are resolved?

It still needs reviews and the merge of tvdb implementation's PR.

[Gauvino]

The merge of the tvdb is done

The merge of the tvdb is done

Now it is yes

Following up on the previous comments about episode mismatch with TMDB:
Do you think it would be a good idea to be able to enable this feature ONLY when TVDB is configured as metadata provider?
As said above, people will not understand why there are a lot of mismatch when they're using TMDB (the default metadata provider) and will constantly ask why there is a "bug".

Yep, I think so. But we should be pretty clear about this - with a tooltip or something.

@gauthier-th Just added a setting to make it optional. And sync only works when TVDB is set as metadata provider for either tv or anime.

Isn't it weird to display an "error" badge when the episode is not available but not released yet? Or not requested yet?

Would an airdate check be enough? IMO the "Unavailable" badge should still appear even if the episode hasn't been requested. This could be changed later as part of the "per-episode request feature" ?

I mean, we don't write the status of a season when it's not requested. We only write "Requested" or "Available"/"Partially Available". Not a status in the error color, implying an error when it's "just" missing

Ah, that makes sense - my mistake. I thought it might be a small UX improvement, but you're right, it could be misleading.

What a great feature ! Hype to be able to request single épisode later !
