I've had this problem with all my videos on my Sony Bravia NX7 kdl-40nx715, i get 2 black marks on the top and bottom of the picture streching it, I've read many solution and apparently the one that works is

if i put it here and i go to my tv the videos appear in thumbnails but when i open them the don't load:
and if I put it here
this message pops up
so if some one could explain step by step where I'm supposed to put "-vf softskip,expand=::::1:16\/9,dsize=4\/3" and how to put it I'd be really thankfull!!
