I agree...there is a correct way to convert 25 to 23.976....but they didn't. I was referring to correcting it. Not sure there is a way to fix it once it's been done wrong....especially when they switch from constant to variable at the same time. I personally dumped the 23.976 versions of His Dark Materials and kept the 25fps.I only find 24fps a nuisance if they have done it badly by starting from a 23.976 source and duplicating the odd frame as required to change the fps (resampling). That IS something they do. If it has been converted (from whatever source) on an exact frame-by-frame basis - either telecined from film at 24 exact or, if from an already 23.976 source, retimed (rather than resampled)(which is also something they do - and which of these it is can only be determined by close examination) then it doesn't bother me at all. There is no material difference. That said, I do tend to convert to 23.976 for the sole reason it is a defacto commercial standard. I doubt you will ever find a commercial BD or UHD at 24 exact.
25 fps can easily be converted to 23.976 (or 24 if you prefer) frame by frame (so, absolutely accurately; no blurring or interpolation); avidemux will do this, frame accurate and allows the audio to be retimed to maintain lip-sync. Doing so does extend the duration - to the "correct" value (for movie content).
They play perfect. Even on the US Blu-Ray version, I could see the jitter.
