Looks OK as long as the waitForEvent function is only ever used on events that are unique enough.

This is pretty strange; expedient but pretty unclear! Probably needs a comment.

They are all unique to media elements except for 'error.' I don't think this is a big problem as other errors on the page should be unexpected. But if you think it is a good idea, I could also check the target of the event and only dispatch the callback if it is a media element.

It ends up being strange because of these special "video" and "mediaElement" global variables. Would be much more clear if they were arguments to the method, but that is more refactoring that I want to do here. Will add a comment.
