In an announcement from Macworld Expo today, Roxio announced that it is presenting demonstrations of its latest product advances and giving attendees in-depth ‘how to’ tutorials, as well as offering special pricing on its complete line of products for Mac OS X. In the announcement, the company said that future versions of Toast will offer High Definition (HD) support. “Support for HD content in future versions of Toast will enable users to import HD program files, such as those created from HDTV capture devices, and automatically create anamorphic widescreen DVDs that preserve the 16:9 aspect ratio.”
