I thought it was just a particular disc, but then I checked a few more to confirm: the black bars on DVDs that have an AR of > 1.78 are not even. I measured. The bottom bar is level - 2" all the way across. However, the top is NOT. The part of the bar in the top left corner is about 1 7/8 of an inch whereas the part in the top right is only 1 5/8 (i.e. a 1/4 inch difference). It's not huge but it is noticeable that the top bar is uneven. Is this a 'geometry' problem? If so how do you correct it? Via the TV or the DVD player? If it is not a 'geometry' problem, what kind of problem is it and how do you correct it? Thanks for the feedback!
