2:3 pull-down, 24fps: thats what the Samsung HL-S5087W 1080p can do. Can someone explain what it means and if it is helpful? I heard 24fps has something good to do when it comes to HD-DVD Movies.

Here's a pretty good explanation of 2:3 pulldown:

http://www.zerocut.c...h/pulldown.html

24fps is 24 frames per second. It's just saying that at 1080p that tv can handle 24 frames per second. I would assume it can actually handle more than that, but I'm pretty sure that most (or all) current 1080p sources are only 24fps. However, the 1080p standard allows for up to at least 60fps, and I would assume the tv could handle that.

Well it says my Samsung 5087W can do 2:3 pulldown, 24fps and was wondering if this is a good thing or not?

Yes, it's a good thing.

It manages the transition from film shot in 24 fps to your progressive display.

If you want to understand what this means, this is the best link I've seen:

Yes it is a good thing, film is 24fps, so if you can do multiples of that you can eliminate judder issues.

Chris, Doesn't this 3:2 really only apply to any scaling of 480i material that the set receives? If it receives 480p/720/1080i/1080p won't the 3:2 pulldown already have been done?

not necessarily. DVD is all 480i so 3:2 pulldown is pretty important.

What I mean is, doesn't the DVD player do the 3:2 pulldown, so why does it matter for the display? Same for HDTV. Isn't a 720p signal already been through the process at the station or the receiver where the TV doesn't actually have to do 3:2?
