CloneDVD2 audio settings

There are two section on the page for "Audio and Subtitle Settings"

In the right pane there is "Stream preferences" and in the left pane it is called "Stream configuration"

They interact with one another and I'm confused the exact difference between the two.

 

Does 'step 5' of this guide help.

Thanks, but that doesn't help. I read this (which is far more detailed) but it still didn't help;
