Many TV broadcasts are broadcast with title=generic_name, subtitle=always_unset, epg_text="Here goes the subtitle mixed into prose". Therefore you get a lot of "foo-generic_name-timecode.ts" files and unless you manually write down the EPG data, you'll have a bad time.

I suggest creating a file called "foo-generic_name-timecode-epg.txt" for each of these files, containing all the EPG data for the broadcasts covered by the .ts-file.
