From the developer:
Update Toast 5.2.1 Titanium or later to 5.2.3 (compatible with Mac OS 9.1 and higher, including Mac OS X v10.3 )
Toast 5.2.3 Titanium enables the Buffer Underrun Prevention option for combination DVD+R/RW and DVD-R/RW recorders when using -R/RW media. Buffer Underrun Prevention is not an option when using +R/RW media, since the recorder uses the built-in error prevention that is part of the +R/RW specification.
