Sonic Adds CustomFlix On-Demand Publishing to DVD Producer

Provides DVD Authoring Professionals with Simple and Cost-effective Title Distribution

Los Angeles, California (December 10, 2002) – Sonic Solutions® (NASDAQ: SNIC) and CustomFlix Labs, Inc., announced today at the DV Expo Convention that Sonic DVD Producer™, Sonic's leading professional solution for DVD authoring, incorporates access to CustomFlix's easy and cost-effective title publishing service.

DVD Producer features an extended palette of powerful authoring and design tools that streamlines the process of creating advanced DVD titles and provides all-in-one convenience for producers of professional DVDs. With the addition of the CustomFlix on-demand publishing service, which is accessed directly from within DVD Producer, content designers have a complete concept-to-delivery solution to get their DVDs into the hands of customers quickly.

Once a DVD has been created using DVD Producer, users can send their completed project to CustomFlix, who handles production and merchandising of the title, including creation of a personalized e-store with a 60-second streaming trailer, on-demand duplication, order management and shipping. The content holder retains total control and ownership of their title, with a minimal "pay-as-you-go" fee provided to CustomFlix as orders come in. High-quality Mitsui Gold DVD-R media used by CustomFlix, as well as full-color package printing, ensure a shelf-ready product with a professional image. "Professional content designers depend on DVD Producer to run their businesses," said Rolf Hartley, General Manager, Professional Products Group, at Sonic. "By adding CustomFlix on-demand publishing to DVD Producer, our users gain an invaluable resource that maximizes their time and money distributing titles. "As the leading provider of solutions for consumer and professional DVD creation, Sonic provides us with a great springboard for bringing the CustomFlix service to DVD title producers," said Dana Piccolo-Giles, President of CustomFlix. "On the heels of including CustomFlix in MyDVD™, we are pleased to see that Sonic continues to support CustomFlix by incorporating our technology into the company's professional product lines, which are the industry standard."

Sonic DVD Producer is currently available through a complete network of value added resellers (http://www.sonic.com/resellers/). Sonic customers also receive exclusive discounts and other offers from CustomFlix when they use this service.
