I think this is mostly a problem with LCD's. I think the OP has a Sammy plasma and I have a Panny plasma and honestly can't really tell much if any difference between 24 and 60.

It isn't an LCD problem, let's not get anyone confused. Read the article posted above, it is natural for 24p to have judder. If you go watch a movie in the theater, you can see it there. So, you will see 24p judder on a plasma as well.

I will state this, though. One of the firmware upgrades on the BDP-S350 reduced this judder drastically. The beginning of Harry Potter OOTP had it really bad when panning down on the playground. It is there still, but at about 40%.

Exactly why I turn off 24p

I have a Yamaha BD-S2900 blu-ray player that goes to a Pioneer Elite Pro-111FD that both support 24p. When I read about "24p," I admit, I didn't really understand the benefits. This is one of those things where most people won't notice a major difference. Here's what I determined:

I played one of the Austin Powers blu-ray movies with 24p disabled on both the blu-ray player and plasma TV. When the movie starts and the animated title ("Austin Powers") scrolled upwards towards the center of the screen, it was definitely shakey and jittery. It wasn't so bad that I thought something was broken. And I think many people might not of even noticed, but it was definitely not smooth.

Now......

I then swithed on 24p on both my blu-ray player and plasma TV and watched the same scene again to see how that scrolling movie title behaved this time. This time, the "Austin Powers" title scrolled up to the center of the screen with absolutely no shakiness or jitter. It was silky smooth and much more pleasant to watch.

Although the purpose of watching movies is not to focus on reading and analyzing the text that comes onto the screen, it does help us better understand how much smoother things can look in a movie when played back on a player and TV capable of supporting 24p.

Based on this analysis, I can only assume that movies filmed in 24p that have scenes with alot of motion (waterfalls, car chases, battle scenes, etc..) will benefit from being played on a home theater system that supports 24p.

Hope this helps.......

The judder doesn't bother me. For kicks though, I will turn it off tonight and watch a movie and see which I like better.

I also turned OFF CineMotion, and left Motion Enhancer ON at High.

Here is a description of what they do in case your HDTV has similar features:

CineMotion - Select Auto 1 or Auto 2 to automatically detect film content and apply a reverse 3-2 pulldown process. Moving pictures will appear cleaner and more natural looking. Select OFF to disable the detection.

Motion Enhancer - Activates Motionflow to enhance the smoothness of picture movement and to reduce blur.
High - Provides smoother picture movement such as for film-based content.
Standard - Provides smooth picture movement. Use this for standard use.
Off - Use this setting when High or Standard settings result in noise.

Motion blur and judder is most certainly a problem with LCD.

Motion blur wasn't a problem until someone pointed it out...

So with Cinemotion turned off and 24p turned off, the opening scene to Fast and Furious looked good, smooth as silk. But honestly, I like the 24p better.

I prefer 24P as well. I will not call 24P movie-like-frame-motion judder. When 24P is off, I can see uneven jerkiness which I would call judder.

Cool,

At least you can see what I mean

. I like 24p sometimes, but judder bugs me, and I really do get better motion from all Blus with those settings.

So it's a draw

I must say though...after watching stuff with 24p off for a while now...I prefer it. Thanks for humoring me.

I think I may have found a new favorite...no 24p! I turned 24p off on the player and turned cinemotion on. Smoother and more natural looking. I think I like this.

To add to it, it keeps the lines clean and the image crisp.
