Exhibit 99.1

                   Sonic Solutions Updates Financial Guidance

     NOVATO, Calif.--(BUSINESS WIRE)--Nov. 8, 2006--Sonic Solutions(R)
(NASDAQ:SNIC) management provided updated financial guidance during its second
quarter ended September 30, 2006 earnings conference call today.

     For the third fiscal quarter ending December 31, 2006, management
anticipates net revenue, on a GAAP basis, will be between $39 million and $43
million; fully diluted earnings per share will be between $0.14 and $0.21; and
non-GAAP fully diluted earnings per share will be between $0.19 and $0.26. As of
April 1, 2006, Sonic adopted Statement of Financial Accounting Standard No. 123R
("SFAS 123R"), "Share-Based Payments." The non-GAAP earnings per share forecast
for the third quarter ending December 31, 2006 excludes the impact of the stock
option expense pursuant to SFAS 123R, the amortization of acquired intangibles
expense to be recorded in the income statement, and the one time write off of
acquired in-process technology expense associated with the acquisition of
SystemOK, which Sonic forecasts will be approximately $0.02, $0.05 and $0.02 per
fully diluted share, respectively, before being adjusted for income taxes. Given
the significance and non-cash nature of these expenses, and for the reasons set
forth below, management has excluded such expenses from the non-GAAP earnings
per share guidance.

     Additionally, Sonic's management expects net revenue to grow by 20% or more
during the Company's 2008 fiscal year, with seasonal revenue patterns consistent
with those experienced in prior years.

     About Non-GAAP Financial Measures.

     To supplement Sonic's updated financial guidance for the third quarter
ending December 31, 2006, management is providing high and low forecasts of
non-GAAP fully diluted earnings per share. Management does not itself, nor does
it suggest that investors should, consider such non-GAAP financial measures in
isolation from, or as a substitute for or superior to, financial information
prepared and presented in accordance with GAAP. Management believes the non-GAAP
presentation is useful to investors because such presentation excludes non-cash
expenses of equity-based compensation relating to SFAS 123R, amortization on
acquired intangibles, and the one time write off of acquired in-process
technology expense, which offers investors a better understanding of Sonic's
core operating results and budget-planning decisions. The excluded expenses do
not result in ongoing cash expenditures and, in management's view, do not
otherwise have a material impact on Sonic's ongoing operations. In addition,
Sonic's financial results for the third quarter ended December 31, 2005 did not
include non-cash equity-based compensation expenses; therefore the exclusion of
non-cash expenses of equity-based compensation facilitates comparison of Sonic's
projections for the third quarter ending December 31, 2006 and the operating
results for the third quarter ended December 31, 2005. Additionally, the
exclusion of the one time write off of acquired in-process technology expense
improves the comparability to our results for the third quarter ended December
31, 2005, since there was no comparable expense during that quarter. Sonic
further believes this non-GAAP presentation is useful to investors in allowing
for greater transparency with respect to supplemental information used by
management in its financial and operational decision making.

     Management uses these non-GAAP measures internally to plan and forecast
future periods, to establish operational goals, to compare with its business
plan and individual operating budgets and to allocate resources. The economic
substance behind the decision to use these non-GAAP measures is an increase of
approximately $0.05, tax adjusted, per fully diluted share over the comparable
GAAP measures. Material limitations associated with the use of these measures
versus the comparable GAAP measures include the fact that our competitors, who
each have their own unique operating and acquisition history, may address the
impact of acquisitions, the one time write off of acquired in-process
technology, and/or adoption of SFAS 123R differently. Management compensates for
these limitations by providing full disclosure of the effects of the non-GAAP
measures, by presenting the corresponding GAAP financial measures in this
release and in Sonic's financial statements and by providing a reconciliation to
the corresponding GAAP measures to enable investors to perform their own
analysis.
