A question that doesn't seem to be answered: what is the sample size being used on colourlike?

The program works by taking a 'read' of a sample clip, averaging what the frames are like, arriving at a single answer and applying it to the full range of the replacement video.

Are the screenshots a sample of 1 frame applied to 1 frame? The entire scene? Large chunks? The entire DVD (which shouldn't work because the color timing is so different between scenes)?

Just single shots like this don't really prove anything.
