so is this thread about how to control your 12yrs old kid from hacking your daddy Media center?
kids gonna find a way, no matter what you do, until you are a better hacker yourself. if your 12 yrs old is a hacker, he will find a way no matter what you do to your media center. how about get him a PC and let him do what he wants... and teach him from right and wrong.
the best way for him not to hack your Media Center is to turn off your media center. pull the plug.
