I understood Cinema mode to be a feature that corrected 3:2 pulldown so
that each frame was shown 5 times at 120 Hz.

It's actually doing it on a field by field basis, for interlaced output.
If the source is progressive and they are outputting p24 as p30, then
there is an inserted frame ever 4 frames to make 5 frames.  That would
actually look worse.

The big question is, what is actually going over the wire between DVD
player and TV when p24 content is playing.  If there is composite output
then you might be able to check on that with an oscilloscope.

Can you lock it into 24fps mode?
