Comment (by gjdfgh):

 This is because the mkv contains the framerate as header:


 {{{
 |  + Default duration: 239.790ms (4.170 frames/fields per second for a
 video track)
 }}}

 That's pretty annoying, but there are files like this around. It would be
 nice if the API could distinguish possibly incorrect hints from the
 header, and actual framerate.
