Apple has released an update to its professional DVD mastering software, DVD Studio Pro 1.2. The free update adds support for external FireWire drives that use the Panasonic combination DVD-RAM/DVD-R mechanism, such as the LaCie DVD-RAM/R drive, and includes a number enhancements to the process of creating DLT tapes for use as replication masters, particularly with solutions that use copy protection technologies, such as Macrovision and CSS.
