Apple has updated its Mac OS 9 Authoring Support package to version 1.1.5.

The package is available for download today.

Authoring Support is intrinsic to Apple's DiscBurner software. The update fixes some issues found when burning from iTunes and DiscBurner, and adds support for new CD-R drives. In its explanatory notes, Apple reveals that CD-R manufacturers often use several different mechanisms in the same CD-R product.

The update adds support for several CD-R mechanisms employed by Sony. There's a complete list of supported FireWire and USB CD-R drives kept on Apple's Web site.
