As a general rule of thumb, folks don't like answering questions in extremely long threads, because odds are the answer is already somewhere else in the thread. So the first thing you should do is search the thread for your answer.
That being said, I don't have a Samsung player myself, and I have no experience with BD wise.
However, it seems to me, it would be easier just to set the player to output 1080p/24 as long as your TVs are 120hz, which I'm sure your LED LCD TV is, as for your other LCD TV, it may or not be 120hz, but all you have to do there is look at the box.
Setting it to 1080p/24 is the highest quality setting, and that way you know exactly what your getting, which is what the player should be sending anyway, but why leave it to chance?
