The refresh rate thing only applies to LCD TVs. It is their attempt at preventing motion blur and ghosting. Additionally, the refresh rate has nothing to do with the frame interpolation. It is just that the set makers figured rather than show the same frame a multiple of times, why not try to interpolate the motion between this frame and the next? The reason why they shouldn't is because it makes movies look very un-film-like. Luckily that can be turned off, while keeping the beneficial higher refresh.

Plasma TVs are based off of the same old phosphors which were used to standardize NTSC color. They're glow has a decay rate which is very well suited to the 60 Hz of normal material. The problem is at 24 Hz for film, the pixels have dimmed too much. So Pioneer does display the same film frame 3 times at 72 Hz to prevent flicker.
