FileBot - automatic renaming utility for TV shows

FileBot is an Open Source, cross platform renaming utility, targeting TV shows.

Main features:¹⁾

• Rename hundreds of media files in a matter of seconds
• Fetch episode lists from TVRage, AniDB, TV.com, IMDb or TheTVDB
• Series / Anime name auto-detection
• Download subtitles from OpenSubtitles, Subscene, Sublight or SubtitleSource
• Reverse rename files using internal history or the original torrent file

I wrote an article about it, see FileBot for screenshots, installation instructions and usage tips (e.g. how to get localized episode names).
