Item 7.01 Regulation FD Disclosure

On June 15, 2010, Sonic Solutions and DivX Inc. each filed notification and report forms under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), with the U.S. Department of Justice and the U.S. Federal Trade Commission with respect to the proposed merger between the two companies announced on June 2, 2010. At 11:59 PM on July 15, 2010, the waiting period under the HSR Act expired.

Additional Information About the Proposed Merger and Where You Can Find It

This Form 8-K is not a solicitation of a proxy, an offer to purchase nor a solicitation of an offer to sell shares of Sonic Solutions, and it is not a substitute for any prospectus, proxy statement or other filings that may be made with the Securities and Exchange Commission (the “SEC”) with respect to the proposed merger. On July 13, 2010, Sonic Solutions filed a registration statement on Form S-4 containing a preliminary prospectus and joint proxy statement (the “preliminary joint proxy statement/prospectus”) with the SEC. When such registration statement is declared effective by the SEC, investors will be urged to thoroughly review and consider the final joint proxy statement/prospectus and any other documents filed with the SEC as they will contain important information. Any such documents, once filed, will be available free of charge at the SEC's website (www.sec.gov).

Sonic Solutions, DivX and their respective directors, executive officers and other members of their management may be deemed to be soliciting proxies from stockholders of Sonic Solutions or Divx in favor of the merger. Investors and stockholders may obtain more detailed information regarding the direct and indirect interests in the merger of persons who may, under the rules of the SEC, be considered participants in the solicitation of these stockholders in connection with the merger by reading the preliminary and definitive joint proxy statement/prospectus regarding the merger, when filed with the SEC. Information about the directors and executive officers of Sonic Solutions may currently be found in the preliminary joint proxy statement/prospectus. Information about the directors and executive officers of DivX may be found in its definitive proxy statement filed with the SEC on April 20, 2010. These documents will be available free of charge once available at the SEC's web site at www.sec.gov or by directing a request to either Sonic Solutions or DivX.
