Did you you use the "use maximum quality" option in the little contextual menu on center right of the export window ?
I never understood why it's hidden there, but do forget about fast renders with this enabled, hope that helps...
On a side note, Procoder alone costs about as much as the entire Adobe suite (at least it did when we got the 2.0 version, so you would expect a bit of improvement :-)
