         Re:   Registration Statement on Form S-1

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-1, as amended,
filed by InterVideo, Inc., a California corporation that intends to
reincorporate into Delaware (the "Company"), with the Securities and Exchange
Commission in connection with the registration under the Securities Act of 1933,
as amended, of 4,025,000 shares of the Company's Common Stock (subject an
over-allotment option up to 525,000 shares of the Company's Common Stock granted
to the underwriters) (the "Shares"). The Shares are to be sold to the
underwriters for resale to the public as described in the Registration Statement
and pursuant to the Underwriting Agreement filed as an exhibit thereto. As legal
counsel to the Company, we have examined the proceedings proposed to be taken in
connection with said sale and issuance of the Shares.

         Based upon the foregoing, we are of the opinion that the Shares, when
issued in the manner described in the Registration Statement, will be duly
authorized, validly issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendment thereto.

                                            Very truly yours,

                                            WILSON SONSINI GOODRICH & ROSATI
