Two comments on these issues:

- The Debian and Ubuntu Linux distributions unfortunately use a fork of
  the FFmpeg libraries called libav. This fork never worked
  correctly for ASS subtitles: in the best case, they appear for a very
  short period, but never as intended.
  When build with the proper FFmpeg, ASS subtitles work fine.
  This issue (and others) is now at least two years old:
  https://lists.nongnu.org/archive/html/bino-list/2012-03/msg00026.html

- I also saw the problem of i/o errors on seeking and sometimes on
  end-of-stream (not sure if video stream or subtitle stream). The
  error message comes from FFmpeg, but maybe Bino uses FFmpeg wrong for
  this use case.
  To test this, one could try the same video/subtitle combination in
  VLC and ffplay. If these work fine, then it is Bino's fault. If they
  don't work, then something in FFmpeg is probably wrong.
