Basically all the warranties I have read, even the extended ones all state the warranties will not cover your screens if one continually plays movies with black bars at the side or top/bottom. WELL now that all these new movies use the aspect ratio 2.35:1 we don't have much choice. Unless one zooms in and cuts off the edges we have to have the top/bottom black bars. Can't believe the movie industry has done this again to us. Business I guess.
