Most Blu-rays run at 23.976 fps, UK uses 24 fps and are region "B".
There is the odd one that is 24 fps and is region "A" eg "The Christmas Candle" (converted for North America, but left at 24 fps)
If Power DVD (what ever version) reports 23, it's actually 23.976 fps, there is no such thing as 23 fps.
Just like my NVIDIA control reports either 23 or 24, also 30, 60 and 59 fps (59.94 fps).
It reports this and gives these choices because that is what my projector can deal with.
Most displays are capable of accepting 23.976 and 24 fps, if they can't, then 3/2 pull down is used so they can be played back at 30 and/or 60 fps.
Frame judder occurs from a bad 3/2 pull down process.
It's also a natural occurrence from too low a frame rate used and it's very noticeable when the camera pans.
The industry could go to 48 fps, but everyone would complain that it's too smooth and unnatural looking.
As you know Power DVD has an auto frame rate detection and this pop up tells you that your frame rate doesn't match your display, would you like to change it.
IMO, this function is not very good and I don't use it, tick the box not to show this again and close it off. It tells me this even though I know for a fact that my frame rate in te NVIDIA control panel is correct for the Blu-ray.
By disabling the auto frame rate function in Power DVD the 3/2 pull down process is totaly done by the video card on your PC and it should be much better
