I know the episode filename should more or less contain old the info, but parsing Name/SxE/Title is always a bit fuzzy, and there is always a good chance data will be misinterpreted. Thing is, I have all the data so I could properly link it.Well, actually the database has enough data for tagging almost all episodes it stores. The names for the movie files and for the subtitles should provide enough data for this. I outlined it before and in a related post.
The benefit of episode support in the API would benefit searching by season and episode (it's very common to have subs in the database that are not linked), like it's possible in TVSubtitles
Actually I could submit much more meta information like codecs, bitrate, fps, etc... but maybe i'm dreaming here
