I don't think you understand what load() does. It certainly does not replace
a currently playing resource with a new one without glitches. When you load
a new resource, you set the currentSrc to a new resource URL, then call
load() and it will reset the player controls to start at the beginning, it
will reset the currentTime to 0 and basically do a whole reset. In fact, it
will even start playing back the element, even if it was set to pause before
(this happens in all browsers and I find that kinda strange actually). So,
all we would need is to also reset the player to pause if it was paused
before or it had reached the end before and also reload the poster.
All you would need to do then for your player is to register a callback that
calls load() when the ended event is raised.
