DLP's get their dynamic range by duty cycle modulating the individual colors for each pixel. The possible different algorithms to do that must number in the gazillions, and could be changed as software updates. Bottom line, the only thing to do is test with the actual playback material and projector to be used. That being said, most of them probably switch fast enough as not to be a problem.
Shooting S16MM at 24fps of an actor standing in the beam of an image playing down from a DLP projector. Will there be any flicker? I have no idea how these projectors work. Anyone?

Better to be safe than sorry.

I wouldn't see any reason for there to be any flicker with film
What do you think the film shutter does? The question is whether the projection of a video image would cause problems on the screen. Are you projecting things off a computer? Then maybe you can full around with the cycle speed or whatever it's called. Personally you need to run tests and maybe fool around with shutter speeds, especially if the actor is just staying still or something.

Also we noticed alot of RGB strobing on forground objects moving through the frame as you can see in this image:

Is there anybody that has obtained flicker with a DLP projector? Should I invest in renting an LCD projector or would it make no difference?
