I think might be too much work, why would a user go through all that 
trouble? I think it would be best to make the automatic screenshot as 
good as possible (I myself had been thinking of taking a screenshot 
somewhere around the first 5% or 10% of the program) and support it with 
a manual system where you can select your own moment. It's just a 
one-time thing so no configuration should be necessary IMO.

Exactly what I had been thinking too, I think this would be a _great_ 
(and then do the same for the videos ;-)
