to be honest, think i mixed things up.
i realized the subtitle tag is missing in some of the recording, so i don't have a clue how it should work.
when i upgraded from 2.2.x i extracted the cutom rename string, and i think i did a copy paste error here, and ended up with names like "- recorddate.mkv"
this overwrote all conversion tasks of the day into this single file.
but just curious, as i didn't find an explanation.
what is this imdb and TVDb ID for ?
