I got tired of waiting for this fix, so I just cancelled my subscription. I’m going back to my previous solution of running Kodi (on different hardware) instead.
This definitely feels like a much-needed and highly desired feature that’s missing.
As a fellow anime fan that’s had to mess around a lot to get Infuse to recognise my collection of shows, we either need the option to override the show’s metadata locally or refer to TMDB’s ‘Episode Group’ section and choose from one of those.
Seeing how users can edit TMDB and create their own ‘episode group’, it would enable plenty of people to either choose a structure they prefer or create the one they want and have it be accessible for others to use.
Hopefully this is something the Infuse team will eventually incorporate.
I feel this.
Generally it’s a good approach to focus on what the “majority” want to see in terms of feature updates, the issue is it’s usually superficial stuff like “new homepage layouts” or which side of the screen the show or film’s description sits - meanwhile long-term users (that likely paid for the lifetime sub) are waiting years for their cartoon or anime collections to be organised correctly rather than how they were aired.
I get dealing with the loudest group first but at some stage you need to focus on the niche areas - if they improve the customisation of how the media can be organised they’ll likely develop a huge support group for that niche and obtain lifelong members.
Sure, if you’ve bought the lifetime sub what does it matter but ultimately you want customers to stay and recommend your service to other people which won’t happen if they migrate somewhere else. It’s not about current business, it’s about future customer growth too.

Can we please get an ETA on this feature. Both Plex and Jellyfin offer this feature which I feel is quite necessary especially when there are files which combine episodes. It is not as big of an issue if the fix was to rename a file, but sometimes, the dvd combines 2-3 episodes which messes up the metadata fetching for all the other episodes following that
Looks like this is scheduled for 8.4.x??? So looking forward to both 8.4 and 8.4.x based on the feature lists; so many things that I’ve been waiting for! With those this will be a plex-killer for sure!
Where are you seeing this info specifically? I can see that it has the planned tag but unable to find any info about what version of Infuse it will be coming out with
Edit: Nvm, I see it now. Pretty excited for this!
Please make sure Emby episode order is supported, in direct mode. All the data is already there and the order should be respected.
