Make sure you are using the BD player input to adjust settings for this player. This includes color, contrast and sharpness settings as well. You can use a Blu-ray movie with a THX optimizer (such as Pixar's <em>Cars</em>) to adjust video settings. For your TV start with "Movie" mode. You should try turning Auto Motion Plus off. This is a processing I talk about in the article which is intended to smooth out film, but it just makes it act weird.

Is there any setting/s that we should be using to adjust this problem? We have a Samsung Blu-ray Player BDP1500 and a Samsung LN52A750 and the movie images appear to are move too fast.

For some reason the LCD manufacturers show the one frame and then interpolate four intermediary frames. Some TVs can do both though. I forget which ones.

The 120 rate is actually 30hz x 4, so film 24fps is converted to 30fps, which introduces judder, and then additional frames are "interpolated" to 120fps, so it almost looks smoother than reality. (It actually can look wierd, especially on film source material.) I can't believe it is still so difficult to see through the marketing language, but to my knowledge, no LCD's display 24p. The big question is why do LCD manufacturers refuse to simply display the true movie frame rate? Is LCD technology not capable of it? I want NO JUDDER! “Starting this year, several companies have started manufacturing LCD panels with 120Hz refresh rates. 120 can be divided by both 24 and 30 with an even number of frames.”
