Marin County, California (September 25, 2001) - Sonic Solutions (NASDAQ: SNIC), the world leader in DVD production systems, announced today a significant enhancement to its eDVD technology, which enables DVD authors to seamlessly connect DVD titles to the Web. Sonic eDVD now includes InterActual Technologies Inc.'s new Player 2.0 and engine technologies. The new eDVD player application will be included as an output option in Sonic's professional DVD authoring applications.

"More DVD titles are produced with Sonic authoring applications than all other systems combined, so we're delighted that Sonic is putting our web connection technology in their users' hands," said Todd Collart, President and CEO of InterActual Technologies. "Now, with InterActual Player 2.0, Sonic can deliver on the promise of broadband through the convergence of DVD and the Internet ."

About Sonic eDVD
Sonic eDVD implements Hollywood-standard Web linking technology with the DVD format, providing authoring facilities the power to create compelling web-connected DVD content without having to code in HTML or Java. By simply attaching a URL to a DVD menu button or within motion video, eDVD authors can enable web-connected viewers to easily jump to a web site. Using an integrated XML engine, Sonic's DVD authoring applications automatically convert URLs and other web events into XML code that is compiled by the integrated InterActual DVD engine into the runtime software required for PC platforms. This runtime player, automatically included in each eDVD title, directs the navigation on the DVD title to ensure perfect Web-connected playback.

About InterActual Player 2.0
The InterActual Player 2.0 is the only enabling software application to bridge the worlds of DVD-Video and the Internet in a single, cross-platform environment. The player, which automatically loads and runs from eDVD-enabled DVD titles on the PC, directly links to the DVD-Video player resident in the computer and presents the user with a new user interface which combines DVD-Video, web browsing and support for Macromedia Flash playback. With such a highly-integrated, multi-platform environment, content developers are free to focus on authoring a rich web-connected DVD experience.

"The InterActual 2.0 Player is the most powerful way to connect PC-DVD users to DVD content owners," said Jim Taylor, Chief of DVD Technology at Sonic. "Combining the superior video experience of DVD with the interactivity and connectedness of PCs and the Internet makes a quantum leap beyond stand-alone DVD titles or streaming video. Now that eDVD includes the new InterActual Player 2.0, it's easier than ever for professional DVD authors to create engaging WebDVD environments for their clients and end users."
