I have had a TV serie with incorrect matching. No matters what I do in the NFO & Files Naming, there is not solution (I will post this into another post).
However, I have realized that going episode by episode, and telling Infuse to read local nfo file, corrects the problem.
As you can imagine, if I have a TV Serie with more than 100 episodes, it will be a nightmare to go one by one correcting the information.
I would like to suggest you introduce a folder option to use all metadata from file from a folder structure.
Right now, from a folder, all you have is "use local metadata" or "use online metadata", but that doesn't solve the problem, since It is always going to TVDB to look for the TV Show / Episode.
Would be great a "bulk" option for all the files into a folder.
