Roxio today announced that its popular Toast 6 line of software will soon be DVD Double Layer (DL) compatible, allowing Mac users to take advantage of this technology for the first time. The new DVD+R Double Layer capabilities of Toast 6 Titanium and Toast with Jam 6 will enable users to burn nearly twice the amount of personal data (from 4.7GB to 8.5GB), or record more than three hours of MPEG-2 (DVD-quality) video content on a single DVD+R DL disc. Users will also have the ability to back up non-encrypted DVDs without having to first compress the dual layer into a single layer, a step which sacrifices video and audio quality. All registered Toast 6 Titanium and Toast with Jam 6 customers will be able to update their software using a free download available in June from the Roxio’s Web site.
