 Chrome 33.0.1750.152, OSX 10.9.2

 As of the bump from MediaElement 2.13.2 to 2.14.0 in [27811], the display
 of an embedded MP4 with `[video]` in MCE spikes processor usage to 100%
 and crashes the tab in Chrome.

 If I revert back to 27810, the view works as expected. If I use
 MediaElement 2.13.2 with current trunk, the view also works as expected.

 If I use the `[playlist]` shortcode, everything works beautifully in trunk
 with 2.14.0. This new media stuff is fantastic. :)

 Safari 7.0.2 freezes as well, though I haven't tested it extensively.
 Neither Opera or Firefox freeze, though both show only text -
