Let's say I have this rather, erm, curious brother of mine, and on our Netflix subscription, he's been watching Mythbusters: Biggest Explosions, Clifford's Really Big Movie, Arrested Development etc. none of which I, my mom, or my sister really want to let him watch. But he has the remote/mouse/computer, so I can't really stop him (revoking a device from Netflix has an overnight turnaround). Keep in mind, too, that these all have different ratings.
Is there any to block out individual shows on Netflix via parental controls?
