[MacDV] Audio for the web.

[Lanny Cotler]

Going back to this to ask as question of anyone who got into this.

The Advanced button to iTunes preferences. And them > Burning. It 
lists the burner on my machine that does the burning. However, it 
doesnt give me a choice. I have two burners, and I'd like to use the 
one that isn't pre-selected. Does anyone know how to change this 
"default"?

TIA,


Lanny
