Bugfix: don't autorewind if someone seeks to the end while paused.

Browse Source 
Feature: if there is no metadata telling us the duration, well then
we're up the old poo river. But what we can do is whip out our
trusty paddle and continually call the highest position we've seen
the duration. It makes playback a little weird, but allows seeking
and so is a step in the right direction.
