not downloading a youtube playlist with numbered prefix

[saturdayxiii]

I'm having the same problem, unless I'm just doing it wrong.

I've tried these, but they yield no results, just the "-%(title).200s.%(ext)s" works as it should.: Custom title: %(playlist_index)s-%(title).200s.%(ext)s %(playlist_index)02d-%(title).200s.%(ext)s %(playlist_index).02d-%(title).200s.%(ext)s %(playlist_index).2d-%(title).200s.%(ext)s %(playlist_index)d-%(title).200s.%(ext)s %(playlist_index)-%(title).200s.%(ext)s

Even %(autonumber)s-%(title).200s.%(ext)s just labels every file with 000001.
