John, Once I dialed in my TV I kept my setting the same for all types of programing from TV to Blu-ray. If you are happy with the picture why change anything. The only thing I would check on your Samsung is to insure that you are matching the resolution your player is sending, 720p, 1080i or 1080p to the native resolution of your TV, and little thing like if you want a full screen, letterbox, ect. if those options are available on your player.

A computer once beat me at chess, but it was no match for me at kick boxing.
