25P no-stutter shutter speed.

Also, remember that motion pictures cameras that Hollywood use commonly have a 180 degree shutter, or a 172.8 degree shutter. At 24 frames per second (which is SO CLOSE to 25P that it's not worth noting a difference at all) you'd have a shutter speed of 1/48th, or 1/50th. A 180 degree shutter on a film camera running at 25 fps would give you a shutter speed of 1/50th.
So yes, you'll reduce stuttering by using slower shutter speeds, but to emulate the look of film, use 1/50th in 25P. Make your camera movements smooth and the motion blur will look exactly the same as motion picture film.

pmark,
1/25th will make for a blurry picture. it also let´s in more light which will result in a deeper depth of field. i shoot with 1/50th almost exclusively and it works fine. if i have houses or other vertical details and absolutely need too pan faster i go down to 1/43th via syncro scan, but usually stick to 1/50th.

there are slow moves and fast handheld ones. there is no stutter on this at all on any of the monitors i tried TFT/LCD/CRT. all shot with 25p 1/50th.

Not directly, no.
The faster the shutter, the more light you'll need -or- you'll need to open up your iris to compensate.

Just got back from a little testing session. In bright sunlight, 1/25 helps, but isn't that noticeable. You can pan a little bit faster, but not much. Drawback is that the iris is almost completely closed (which isn't really that much of a drawback -- could be a benefit in some cases.)
After practicing with 1/50 (shutter off), I found what speed to pan at (slow or fast -- nothing in between) to eliminate stuttering.
What makes it difficult is that the stuttering doesn't always show up on the viewfinder or LCD screen -- you have to examine on a CRT monitor afterwards to see if it stutters or not.

pmark, go and watch a DVD. you will suddenly realize that hollywood only pans slow. or they have a subject in the foreground which they follow. find a scene in a movie where the actor crosses a room: check the background: it stutters and strobes. but because our eyes normally stay with the action in the foreground we do not see it really.
there are several ways to eliminate the stutter. search the boards to get more tips. but the best is to watch movies and see how they get around the problem: panning scenes, have foreground action, get a shallow depth of field to blur the background, countermotion (dolly to the left while panning to the right), slow pans or steady shots instead of one fast pan !
P.S.: i just saw a film that played in mexico. when they visited an old temple they panned too fast over the houses. i was like: hell, i would never use that and reshoot it....but they didn´t.....

....Adding to alpi69's relevant comment... Take a look at Saving Private Ryan...
Sometimes a cinematographer will intentionally use a faster shutter to achieve a jittery aesthetic..
Different shutters for different looks.. None of them are bad.. Just think of it as another option
you have to adjust. Try to get the right look for every situation. Sometimes it's smooth and creamy,
and sometimes it should look like you're storming the beach at Normandy. You know?
