I've been using Fairuse Wizard with the Speed Setting, and dragging the slider all the way to the right (quality).

I'd like to experiment with the "Codec Setting." So on the pull-down I choose "Codec Setting" and then I can click on the setting button and make all sorts of changes for DIVX. When I finally click okay and I'm back in the Fairuse Wizard window, it doesn't really seem like any of the settings I've chosen have stuck. For example, I might have made all sorts of bitrate changes within the settings window, yet when I come back to Fairuse Wizard it looks like it is at the default file size of 700 mb (yes I have the full version).

So how can I make use of the Codec Settings?

Thank you.
