Hi, First time on the forum, and I have a question, about a puzzling issue. I have a Panasonic Th-50PZ700U plasma TV, which, in general, I love the way it plays. But since the beginning, I have been plagued by "motion blur", anytime there is some relatively fast movement on the screen. This bluring manifests itself as a reduction in the resolution, to blocky pixels. It also happens if there's a strobing or flashing light in the program source. Now here is the strange part: this only happens while watching cable programs (Cablevision, on Long Island, New York), and it's the same for HD, or standard programming. The cable box (DVR) is hooked up to the TV with a good quality HDMI cable. If I watch a DVD (the DVD player is a OPPO upconverting unit, hooked up with the same quality HDMI cable, as the DVR box), there is absolutely no hint of any motion blur. It's just plain perfect. I contacted Panasonic with this problem (the unit is still under warranty), and I was told that since the DVDs play perfectly, it is probably the cable service. Does that make any sense? The picture quality on cable is quite good, until there is motion. Any help or suggestions would be greatly appreciated! Thanks!
