I have an .iso file that needs to be burnt on a DVD, however, the internal drive I have is only CDRW. So I've hooked up a USB DVD writer which gets recognized (and Toast can burn on it as well), but how can I get the OS-X Disk Utility's burn option to work with the USB DVD Writer. When I click on burn with the iso file selected, it just shows me the internal CDRW with no place to change that.
Thanks
