The title of this article is bit misleading as each airline has their own system, British Airways even having rather different-looking interfaces in the various cabins classes (though the films are the same). The one thing all such systems do seem to have in common is instability. In my experience, the inflight entertainment locks up on about one in four flights without any hostile action from my side. It could of course be someone else experimenting.
You gotta love someone who experiments with these things in public. I do the same thing often getting systems to fall out of their intended use mode.
