any developer reading this or should it be reported somewhere else (-dev)?

thanks for the explanation, i am trying to encode something at 64 kbps
and as i now know that -b 64 works equally to setting a quality and does not
enable --managed i don't need to play around trying different -q switches :)

no need for that, i just feared -b would enable it.

thanks a lot,
