I have been looking for an answer to this and haven't found it. How does TVHeadend go from an Episode number to a subtitle?
The short situation is that while running a self compiled unstable build, I ended up with a bunch of files orphaned named like <tv show name>.Exxx.ts where xxx is the episode number that TVHeadEnd sees. I am using Schedules Direct in the USA for my guide data (works wonderfully) and TVHeadEnd is getting the correct subtitle for the show, but I want to identify which episodes I have to see if they are duplicates of already recorded content. However, without knowing the subtitle or at least season and episode within the season it is a slow process.
Obviously TVHeadEnd is getting that data somehow and I have changed my recording file names to include the subtitle in case of future issues, but I would like to get the files I have figured out without having to watch each one to figure out what episodes they are.
