I've noticed lately that when I'm watching Blue Ray movies that there is some artifact that I cant seem to get rid of. In brighter shots, there is a noticeable flicker (for lack of a better term). It's kind of slight and many wouldnt even notice but I find it ditracting. I tried tweaking the picture size of my TV last week and also did some adjustments of the picture while I was at it and I'm afraid I may have caused the current artifact when I did it. When I say its a flicker I dont mean that it get it gets dark briefly or anything like that. It's just subtle change in light intensity. Any ideas??
