This is a know problem, at least to me.  Unfortunately, I'm not sure
how to fix it.  The problem is that a reference picture used by the
picture being decoded is unavailable, since it was before the point
you started decoding at.

Michael, Loren, what should we do about this?  It used to work, a long
time ago.  IIRC, it broke around the time B-frame support was added.
