  The problem is that you rarely want to use the absolute latest fragment. The
live seek range returned takes into account the "safety margin" that most
protocols recommend (i.e. a few fragments before the latest one).

  Ok, I'll look into it. Maybe we should take into account the fact that
nothing has been downloaded yet.
