This is a good argument against having a paused-poster.
The question then is whether the end-poster needs to be different from
the start-poster. If the main use case is "re-display the poster image
so the user knows that they can play again", then the end-poster and
start-poster don't need to be different.
Showing the poster at the end of playback is a matter of taste. How
about we remain with a single 'poster' attribute, and add a 'showposter'
attibute, with values 'start', 'end', and 'both', which denote when the
poster is shown? Or the values could be enumerated similar to how
readyState and networkState are enumerated.

It seems reasonable to me that subsequent calls to load() should behave
the same was the first call to load(), so the poster should be
redisplayed whenever load() is called. We should change the load()
algorithm to require the poster frame to be repainted, if it's present.
