Another consideration is going to be the different resolutions people
record at. If everyone used the same resolution you could choos e a
few place son teh screen (like a real fingerprint sort of) and get a
difference from a particular pixel or set of pixels (this should
eleminate the contrast and sharpness settings). Then just create a
sort of MD5 type algorthm for frames or something so you aren't
passing the actual screen shots and thus copyrighted material. The you
could look for a series of frames that each match the algorithm's
results in the database for the specific cut point.

All that said with different resolutions you get even more hairy than
what I have described, which is admittedly more complex than it might
have to be. How do you compare different resolutions for the same
picture? I'm sure it can be done.
