Since I have had my 50PF9631D starting in July, I have been using only two of the presets; namely SOFT or NATURAL. I do have the AVIA DVD and will try creating my own PERSONAL settings, but for the most part I like what I see with SOFT or NATURAL. SOFT works for me with brightly lit scenes, such as a sunny day football game; I use NATURAL most of the time for movies and shows. If I ever get around to calibrating with AVIA, I will post my results. It is also an impression of mine that my picture quality is very much a function of what the broadcaster is sending out, with broadcast quality being the biggest factor and adjustments to my TV settings a secondary factor.
