I am new to this so am probably asking a stupid question but here goes anyway.
My new blueray player is outputting a picture with black bands top and bottom whenever I play a dvd disc and with some blue ray discs. However my copy of the "Planet Earth" in blue ray is displayed full screen. I have tried changing settings on the dispay but whenever the player starts the picture reverts to a letter box. Am I missing a setting somewhere or is this something peculiar to my player? My dvd player used to output everything at full screen so I am at a loss as to what needs changing, TV settings or Blue Ray player settings?
