I already sent a bluray player back to Samsung due to it losing the ability to read discs. They replaced it with a newer model which has problems reading DVDs on the first try, but plays blurays right away. It's on our alternate TV, as we have a better set up downstairs, ironically enough using a PS3 as the bluray player.
I vote for Photon's port-by-port theory, as I just switched the settings on our older alternate TV today, and had to do it on all the ports we are using. I just searched the model number, then "calibration" and found settings that made the picture quality so much better.
And as I said, I had to go on to the 3 ports that I have inputs running to change the picture to the new settings.
As for the PS3/Samsung quality, I haven't noticed a difference, although they are on to different TVs (720p vs 1080p).
