do not delete OP01/ED01 or you won't be able to play opening and ending,
also OP01/ED01 should be in same folder as the episode in order to play
opening and ending during the episode....

  I'm gonna encode whole season of this anime so I decided to encode with
ordered-chapters so you only needed to download OP01/ED01 for once and it
will work throughout the series.............. look forward to my encodes
