For the best reproduction of any movies on most displays... you must consider the frame rate and multiply it until your monitor or hdtv supports that hertz rate.
Example (1 fps = 1 hertz):
23.976 fps = 47.952hz (2:2 pulldown), 71.928hz (3:3), 95.904hz (4:4), 119.88hz (5:5).
24 fps = 48hz (2:2 pulldown), 72hz (3:3), 96hz (4:4), 120hz (5:5).
24.976 fps = 49.952hz (2:2), 74.928hz (3:3), 99.904hz (4:4), 124.88hz (5:5).
25 fps = 50hz (2:2), 75hz (3:3), 100hz (4:4), 125hz (5:5).
29.97 fps = 59.94hz (2:2), 89.91hz (3:3), 119.88hz (4:4).
30 fps = 60hz (2:2), 90hz (3:3), 120hz (3:3).
50 fps = 50hz (1:1, no pulldown required), 100hz (2:2).
59.94 fps = 59.94hz (1:1), 119.88 (2:2).
60 fps = 60hz (1:1), 120hz (2:2).
Further details look up wikipedia for 'Telecine'.
Pulldown method simply makes duplicates of a frame in the same amount of time for a better looking image.
The best for 23.976 fps on a CRT is 72hz (3:3) or 120hz (5:5). (CRT blacks is still the best IMHO)
Panasonic PZ series uses a 2:2 pulldown and looking at the above you may select the correct hertz for your fps movies.
Panasonics - Intelligent Frame Creation (IFC) adds an extra frame to any source to make it look smoother and this is most likely used for 23.976 fps movies to 24.976 fps (or 25 fps) for 50 or 100hertz.
This may introduces a audio hasten that needs to be delayed long enough for the extra frame to finish.
(23.976 fps movie /1000= 0.023976 ms/ frame). The 24ms hasten in a 24.976 fps may not be noticeable for a 23.976 source.
An interesting feature in the Panasonic PZ series is the 480hz sub-field drive; which is actually a frame divided into 4 locations for processing and analysing and multiplied by 2 (double scan) for a total 8 sub-field and each field works at 60hz*8=480hz. So the 480hz is a gimmick and the real meaning is:
The pictures sharpness scans a frame in 4 parts x2 (double scan) to produce a smooth, crisp or sharp image frame then connects them with the remaining frames to create the desired quality equivalent to that of a 480hz and this maybe using some sort of 'anti-aliasing' x4 like hq4x (4:1).
Also when it comes to configuring the plasma set for movies:
set the aspect ratio to 4:3 on a 16:9 source for borders and set side panels to off for pure black then match the black borders brightness to the panels borders for the perfect brightness. (and restore the side panels to high again)
To set the colours; increase it to the highest then lower it slowly until the fine details in the colourful movie can be seen and once you found the most colourful with full details visible then your ready for a cinematic expirence. (sorry cant explain it any better)
I'm very much satisfied with my panasonic plasma (with a free 5 year warranty) for its cinema mode that produces quality almost near crt blacks and I would prefer a pioneer kuro's perfect crt blacks but it is expensive.
