It would be nice if we could set metadata in different languages for different folders. I have both English and French movies, in different folders. The software eventually changes all metadata to English even after I’ve set them to French in the French movies folder.
Just as a option until it becomes a feature (if it garners enough support too) you should be able to place a nfo file in the preferred language next to the movie and it should stay in that language.
One benefit would be you wouldn’t have to have a separate folder for languages, just include the nfo file for those movies you want in a different language.
