Something similar to EpNamer that will automatically look up files and rename to a naming convention that is Plex compatable.
Sickbeard does this, even if you don’t want/need to use it for downloading, it can organize and rename files.
I'm using Sickbeard but have had problems with its post processing. I usally just use Epnamer before adding files to my PLex server.
For me i use theRenamer, SubDownloader, and Bulk Rename Utility (as needed)
and it manages to cover all my needs.
I use filebot it can rename download subtitles, the gui interface can be used to bulk rename, but I've just used it for automating my renaming process
