I have an issue on OSX with the keyboard controls. The space (play/pause) doesn't work consistently.
It's like there is a long delay between the time I press space and the time the player get the control command.
This is going on and off, there are times when it's working perfect, pressing space either plays or pauses the movie, and times when it's not working at all.
This happens on a MacBook AIR, with both Safari and Chrome browsers, in all movies (not specific to one).
