He always tells me that it is bad for the TV if the black lines are above and below the screen when watching a mvie that is not formated for our widescreen tv. It drives me up the wall when we get a great movie with excellent picture and we have to play it on "zoom" mode, which cuts off most of the picture. We just finished watching Xmen 2 a couple hours and it was the last straw. So, we thought we'd post the question to get some answers from some more knowledgable people. Will this damage the TV. Given it would only be used as such when watching the one movie once a week, meaning no extended viewing beyond 2 hours. Or will it cause long term effects? We have a 65in rear projection Mittsubishi medallion series tv that was bought new last year. Thanks in advance for helping settle this issue!!!!
