Well, that's pretty much the point of this patch.  I have a script that
executes mplayer using cropdetect to automatically determine how much to
crop.  I can't take a look at the numbers and sanitize them by hand. 
Also, doing any math in a script isn't really plesant, which is why it's
a patch to mplayer.  

Cropdetect needs some improvements, and this was the easiest way to make
it work.  Loosing 1% of the lines doesn't hurt as much as having to
spend several minutes, per video, to determine the perfect crop/scale
parameters.
