2) Every so often motion will jerk, as if the cable box has a problem. But I am sure it's not the cable box, as I've tried it with other inputs.
Anybody else with these issues? Did I just get a bad egg, and maybe exchange it for the same model?
It may be that you have a "lemon", but you should check a few things first. First, when you see these problems, check the setting for MotionFlow. If it is on High, that can cause such problems. Set it to Normal if it is on High or to Off if it is on Normal. Any effect on the problem?
Secondly, I've found that the settings for CineMotion and MPEG Noise Reduction correction, when activated, can cause some strange jerky motion with the some content. When you see the jerky motion, be sure both the MPEG Noise Reduction and the CineMotion are turned off. If they are off do you still see the problem?
If the above don't reduce or eliminate the problems you described, you probably need to be getting a replacement TV or at least warranty service from Sony.
Strange as it may seem to some, I've had the best performance from my 52Z5100 when I've hit "Factory Reset" on the Picture Adjustment panel and left things the way Sony set them up. I've learned to be very prudent in any adjustments to the factory settings and to make small changes, then evaluate the results for days before messing with it again. I've found CineMotion to provide very unpredictable results on both OTA DTV and Dish Network feeds, so I've resigned it to use only when watching DVDs or video tapes. MPEG Noise Reduction above Low is also very unpredictable. Usually you can keep it on Low, but sometimes even Low causes the frame jerking picture you described. Earlier in this thread I warned about the use of Black Corrector. It seems to work great on Low, but anything above that can cause some severe distortions in some content.
