If you are worried about calling this too often, you can do `if (mediaControls()
&& (oldValue != value))` but I think this is not very important because it would
only apply to people doing `video.disableRemotePlayback = true;` when the value
was already true. Probably not that big of a deal.

Done. Missed the fact we get the old value in the parameters.
