On my Panasonic 42pz700 I noticed when watching some movies via HDMI on either my upconverting 1080p pioneer dvd player or blu-ray disc on my ps3 that there is some noticeable minor flicker. I seem to notice it usually in bright outdoor scenes such as sky shots. One blu ray disc that it's quite noticeable is on The Road Warrior. It's very slight kind of like using 60hz on a crt computer monitor. I do not notice it on regular HD channels and most regular dvds seem fine although I did notice a bit on standard dvd RE Extinction using the pioneer upconvert.
Why do you think this is happening, is it HDMI, TV, the dvd players or the transfers?
