I researched the 200 and 220 because I just bought an LG plasma and both support 24hz playback. Cinema Smooth I think. From the manual:
1080p Display Mode
When the resolution is set to 1080p, select
[24 Hz] for smooth presentation of film material
(1080p/24 Hz) with a HDMI-equipped display
compatible with 1080p/24 Hz input.
