In the picture settings menu on my 757ai, there is a setting called PureCinema. (I believe only applies to Prog Scan Component output) The options are On, Auto1, Auto2 and Off. The manual refers only to On, Off and Auto (default setting). A couple of times when playing video-sourced material I have had a combing effect displayed which was cured by changing to off. With dvds that the player flags a film-sourced the picture is definitely better on one of the On/Auto settings. Does anyone know what it actually does? Ive sussed-out what looks best, but am curious as to why.
