well next time shes watching a movie ask her whats going on to the left and right, and when she says she doesnt know, say BECAUSE YOU CAN SEE OVER THERE!
why buy a movie when your not getting it all. and someday when she gets a new TV, every movie she has is going to have even thicker black lines to the left and right.
people have gotten me full screen movie as a gift before, i return em and get wide, heh.
