More poking around getting the media element section to use the new

play()
http://people.w3.org/mike/diffs/html5/spec/Overview.1.1253.html#play
When a media element that is actively playing stops playing because its readyState attribute changes to a value lower than CAN_PLAY, without the element having ended playback, or playback having stopped due to errors, or playback having paused for user interaction, or the seeking algorithm being invoked, the user agent must queue a task to fire a simple event called timeupdate at the element, and queue a task to fire a simple event called waiting at the element.
