Heh, you know, I _just_ noticed the less than and major than signs!
Anyway, I would like to ask another question on bpp: if I specify a too
high value, let's say .50 or .60, to make sure a clip gets out really
well, don't care about space, do you think it's possible that the
countquant.pl script gets confused? I mean, I was getting higher qs 
with .60 than .25. Is that explanable in some way?
