I've noticed some lip sync'ing lately where the video doesn't match the audio. I first noticed from my cable box and then last night I started watching a dvd and started noticing the lip sync. I have the panny 42pwd7uy and the s77 player. Last night I turned off the 3:2 pulldown option, which i still do not know what this does, but the lip sync'ing went away. Is this caused from video or audio processing like the 3:2 pulldown, noise reduction or the AV enhancer? ANyone have this issue? Do I need the 3:2 pulldown option on? Should I turn off all av enhancing options on the display and the source?
