I have a substantial iTunes media library containing both movies and TV shows. This media does not have DRM, and has already been transcoded as necessary for optimal use within Apple's ecosystem.
Each file has accurate and comprehensive metadata including title, year, season #, episode #, cover art, soft subtitles, etc. I rely solely on metadata, and the actual filenames may not be consistent or comprehensively descriptive.
Can Plex automatically consume this metadata without referencing filenames or online lookup services? I have no intention of either editing my metadata or having Plex display conflicting metadata from alternate sources.
