Well, I don't know how the Samsung processes a 24p signal internally. It may not do 5:5 pulldown internally as that poster claims. But, it does something
, and it certainly does accepts a 24p signal (as can be seen by pressing info on your remote during a blu ray). The TV is always processing it's video signal at 120Hz. When it gets a 24fps image, it doesn't show that image at 24fps. The screen update refresh rate is fixed, and independent of the input signal. The screen updates at 120Hz, regardless of input, (just like the screen resolution is fixed at 1920x1080 regardless of signal input resolution).
I'm not claiming that the TV does 5:5 pull down or runs at a native 24Hz rate when receiving a 24fps signal. I'm just claiming it does 120Hz video processing, and displays smooth, judder free playback of 24fps material. I haven't read one post on this thread of someone claiming they were unhappy with the playback of 24fps material, so whatever they are doing (5:5 pull down, 3:2 @ 60Hz, something else), seems to work and be acceptable for viewers. I wouldn't worry about what/how it is doing it, just that it accepts 24fps signals and displays them well. That is what I'm trying to convey by that item in the FAQ.
This is my understanding, and I believe it to be correct. If you (or anyone) would like to propose some rewording, or additions to it, post it and I am happy to consider adding it.

Well, as I said above, if anyone wants to propose an addition or as re-write to that section, post it and lets discuss it!

Well, the technical argument would be "crushing blacks" or "loosing shadow detail". What black adjust is doing is adding extra black at the low end. So, for example say your video signal has colors ranging from 16 to 235, with 16 being total black, and 235 being total white. At various settings of black adjust, it will make everything below (and I'm just making up these numbers for this example, don't know what they really are), say 220 total black. At a higher setting it may make everything below 224 total black. So any parts of the picture that were above 216 that you were supposed
to be able to see, will now be darker and may be totally black, loosing any fine shadow detail. It does have the effect of making the overall black level look better, because the picture is darker, but you do loose some detail. Also, it may adjust it's cutoff levels or interact with dynamic contrast, in how much it adjust blacks depending on average picture level, I'm not really sure.
If you want an easy way to see the effect of this, the AVC HD calibration disk (free download, check the calibration thread) has some great patterns for demonstrating this. Download and burn that to DVD, but you have to play it in a Blu Ray player. There are some test patterns on that disk that show a background at various levels, from black to all white, and ranges of like 25%, 50% and 75% in between. These patters are solid, except for at the bottom right hand corner it also always shows a grey scale from black to full white. You should always be able to see all steps of that gray scale regardless of the background picture level. You can use this image and turn black adjust on to various levels and watch how the lighter shades of black and gray disappear. Also useful for seeing the effects of dynamic contrast.
In the end, it comes down to personal preference if you want to use these settings. I actually sometimes like using dynamic contrast and maybe even some black adjust in standard for watching certain cable channels during bright daylight hours. However, to properly set your contrast and brightness levels, make sure all of these are disabled!
Only turn them on after you have correctly set those.
