Sometimes entire movies are told in the few pixels of a corner.
Do you think James Cameron would be happy if we watched Avatar and few pixels in each corners were missing?
I'm pretty sure James Cameron would be unhappy that your watching his movies in a window on a desktop rather than on a big screen like it was intended.
If these missing pixels bother you, go full screen. Ive checked, they are there in full screen mode. I mean c'mon! this is just silly.
