I also thought about it and conducted an experiment with 60 and 75 refresh rate of full screen and 25-30 frames movie. It does not affect.
Frame rate and refresh rate is VERY important

They should be an exact multiple
ie:
25fps = 50Hz / 75Hz
30fps = 60Hz

or you will see visual glitching (different from frame dropping you are experiencing with movie playback)

As richard posted - see the lock/divide options to lock the frame rate to an exact division of the output refresh rate.
