I apologize for asking such a basic question, but I guess I don't fully understand yet. I recently bought a 50" Panasonic S1 Plasma with a Panasonic blu-ray player. Is it normal to have black bars on the top and bottom of all blu-ray movies, or is there something wrong with my settings? I would like to take advantage of the full screen, especially while watching blu-ray discs. Thanks for any answers and advice in advance!
