I recently shelled out for a new denon dvd-2910 and have been experiencing some picture problems. Bright white patches in the picture are faintly smeared to both the left and right sides of the picture. This problem is quite noticable on a lot of discs. I am hoping it is a simple setting that needs changing on the 2910, brightness, gamma correction etc. rather than a fault. Can anyone tell me what to change please? The screen is a CRT back-projector Sony KP-44PX3U. There are no such problems with another (much cheaper) samsung dvd player.
