No offence but I did not get tender at all. I felt just a bit smashed up but whatever no biggie
Also, I never said that my TV have the option but the ability to run at true 24Hz (via Exact Scan option), it's nVidia's drivers who are telling to TV (with the setting of frequency refresh rate) to stay at 24Hz, the TV of course just brings this possibility to keep the scan as told,
And I must confess it was very confusing of me to tell wrong (which I did not knew yet) things like I've accomplished my perfect playback with DSPlayer was wrong since it was not running at all, this was stupid but again, I'll go edit the threads to reflect the new information I've learned.
At last, yes, you helped me realize what I am using internally and this is useful, thank you.

What TV do you have and frequencies does it run at? A lot of TVs will not have an option that dondre mentions abut frequency settings. Although not as smooth as mulitples of of 24hz running 24fps material at 60hz should not be that jittery. And if you dont have at least 72hz Im going to bet that you are going to run into some flicker as well.
As you may already know, movies are shot at 24 frames per second, but 24 refreshes per second by itself is not enough to remove flicker. Movies theatres show each frame twice giving a 48Hz refresh which is accepted by them (and what most people are therefore used to seeing) as good enough to remove flicker.
Getting a display with a multiple of 24Hz capable means that you will see films in their "
natural" 24 frames per second.
Just having a display refresh at a multiple of 24Hz doesn't mean that it is giving you a X-X even pulldown.
Many 120Hz LCDs give you 6-4 not 5-5.
Note that although most 48-72-96-120 are great and show no flicker, mainly the Panasonic plasmas have problems and at the 48Hz they display many people see flicker.
This is not true of all 48Hz displays.
To show 24 frame source at 60Hz you get 3:2 pulldown; one frame 3 times the next frame twice. This is how we have always been watching movies on our TVs until 24p capable TVs have come along. As noted before, not all 120Hz TVs are applying an even pulldown; many do the standard 3:2 pulldown to 60Hz and then just double it which turns judder/overhyping problems even more obvious.
Also and again the DCDI Faroudja Cinema processing helps fighting against the 48Hz possible flickering, and fore those of us who do not own a TV with such processing technology, there are workarounds out there

On the other hand your point of betting that at 48Hz people are experiencing flickering may be true, there is a little flicker at both field and frame rates but
at 5x viewing distance, it is acceptable and barely noticeable, but to ensure complete removal of flickering at so low framerate, the light output in movie theaters is lowered to reduce flicker (which is also why they double shutter to 48fps). As you pump up the light level at 24fps the flicker increases. Same trick could be used on REAL LCD TVs as well playing with the back-light control...
Finally, to whom the 3:2 pulldown effects have never bothered you then don't need to worry about it (nor seek a solution to it). 24p capable systems just give the opportunity for smoother movies...
In conclusion, SlaveUnit, no my Toshiba TV has no flickering at 48Hz and I've been able to see the new Toshiba 240Hz TV with a 10:10 X-X pulldown, the difference is not as obvious as it is between incorrect pulldown VS correct pulldown.
PS: For those who are questioning why 60p is not better because it could look better due to a superior number of frames per seconds, it is true that 60p has a wonderfully smooth playback, and looks absolutely alive and lifelike on screen I'd say that if you are watching sports and want a "live" feel with perfectly accurate images then yes 60p is awesome. On the other hand, if you are watching a cinematic movie, and trying to tell a STORY then you want to "blur time" a bit and hide oddities and imperfections in actors movements. 24p does just that, and creates a surreal effect that is mostly subliminal, but highly effective. When you see side-by-side footage of both 24p and 60p of the exact same movie scene, the 24p footage looks less awkward in many places during an actor's performance. 60p shows you TOO MUCH temporal information; which is basically great for porn, sports, and news... no so great for story telling.
