Hmm.

Perhaps you and I have different ideas about what is meant by "full 
screen", but why would a page need to hide anything when the video is 
full screen? The page itself won't be visible, because the video will 
be taking up the entire screen!

For the purposes of having video take up the entire space on my monitor, 
the page doesn't need to be any the wiser... it can go on thinking I'm 
viewing it in the little box on their site.

An interesting point to note, though, is that this sort of full-screen 
switch effectively allows the user to bypass any overlaid 
ads/captions/UI that the site may provide.
