Dual burner troubles in DVDSP 4!

Hi
I have the internal SuperDrive, and an external Bravo DVD robot on my G5. When I am in DVDSP and need to burn a disc, the program defaults to the external robot as the burn drive, not the internal SuperDrive. This is annoying since it is not within arm's-reach, and I want to use the internal drive anyways to record master discs. I haven't been able to find any place in DVDSP to assign the internal drive as the primary burner.
Outside of disconnecting the Bravo from the Mac I can't find how to change back to the intwrnal drive,

Any ideas?!
Thanks
