Business Editors/High-Tech Writers

MARIN COUNTY, Calif.--(BUSINESS WIRE)--Sept. 6, 2001

Sonic Solutions (Nasdaq:SNIC) today announced that Adaptec, Inc. (Nasdaq:ADPT) will bundle Sonic MyDVD (Version 3) with its new line of FireWire/1394 products to create a total digital video solution for consumers. Using the Adaptec Dvpics Plus, FireConnect for Notebooks and DuoConnect products, Sonic MyDVD makes it fast and easy to transfer and publish video content on DVDs that can be played on home DVD players or DVD-equipped PCs.

"Sonic MyDVD was the natural fit for Adaptec's entry into DV-based home video," said Jeff Loebbaka, Vice-president and General Manager of Adaptec's Desktop Solutions Group. "Sonic MyDVD makes it fast and easy to publish on DVD, and makes more compatible DVDs that simply play better. That's essential in the home market, where a wide variety of set-top and PC-based players are used."

The DVD-Video format is the fastest growing consumer electronics format in history. With over 30 million DVD set-top players and over 70 million DVD-equipped PCs in the market today, DVD is rapidly replacing tape as the video publishing format of choice for video professionals and video enthusiasts. Using the MPEG-2 video compression standard, DVD video closely approximates the quality of the DV digital video source and can more accurately convey that quality than standard analog VHS tape. The DVD format also offers a high degree of interactivity in the form of menu navigation, support for still images and slide shows, as well as high-resolution digital audio that make it a superior format for archiving, publishing and sharing digital video content.

"Adaptec has emerged as the undisputed leader in DV capture cards for consumers," said Mary Sauer, Senior Vice-president of Business Development at Sonic. "DVD players and DV cameras are two of the fastest-growing consumer electronics products of all time. Now, with the introduction of Adaptec's FireWire/1394 products and Sonic MyDVD, home users can edit their DV videos and produce DVD content that can be recorded to low-cost CD or DVD-recordable drives. This changes the way that consumers share home videos."
