Demand for Sonic DVD Creation Products Continues to Accelerate

Marin County, California (August 12, 2003) — Sonic Solutions (NASDAQ: SNIC) announced today that the sales of its desktop DVD creation applications, Sonic MyDVD® and DVDit!®, have topped the six million unit mark. The announcement of this six million unit milestone has come only seven months after Sonic announced reaching the three million unit mark, and highlights the strength of the DVD burning market, as well as Sonic’s leading position supplying DVD creation software to PC, peripheral and drive OEMs.

We are pleased to partner with Sonic to deliver their award-winning software to consumers.”

Based on the same technology as Sonic’s industry-leading Hollywood DVD production systems, Sonic MyDVD and DVDit! make it fast and easy for home users and video enthusiasts to create DVDs and VCDs of their own videos and photos and add the same sizzle found in Hollywood titles. With the ability to simply drag-and-drop video and audio into a project, design interactive menus and record the final content to DVD+R/+RW, DVD-R/-RW, DVD-RAM or CD-R/RW, Sonic’s DVD applications offer the most flexibility and compatibility of any application on the market. With OpenDVD^® technology, Sonic users can also re-edit their DVD and VCD projects at any time and add and delete content and change menus.

“The accelerating trend of home PC video and photo editing and TV recording, as well as the explosive growth of DVD recordable devices, continues to fuel consumer demand for easy-to-use, high-quality DVD creation software,” said Mark Ely, Senior Vice-president of Strategic Planning at Sonic Solutions. “We’re very excited about the success of our desktop product line, and we’re extremely pleased to be playing such an important role in the growth of this market.”
