OpenDivX license



Hi, I'd like to hear some comments about OpenDivX license that it's attached
below:

DivX Open License 
================= 
Version 1.0

Copyright (C) 2001 Project Mayo.  Everyone is permitted to copy and
distribute verbatim copies of this license document, but changing it
is not allowed.

Provided below is our open source license agreement ("License") under
which we provide the Codec (defined below) to you free of charge. 
Please read it carefully.

BY USING, COPYING, MODIFYING, OR DISTRIBUTING THE CODEC OR A LARGER
WORK (DEFINED BELOW), YOU INDICATE YOUR ACCEPTANCE OF THIS LICENSE TO
DO SO, AND ALL ITS TERMS AND CONDITIONS.

For purposes of this Agreement, the "Codec" shall mean the OpenDivX
compression/decompression software provided to you by Project Mayo
("Project Mayo") and any derivative work thereof, that is to say, a
work containing the Codec or a portion of it, either verbatim or with
modifications and/or translated into another language.  A "Larger
Work" shall mean any work including or integrating the Codec as an
object file or linked library.  "Encoded Content" shall mean any
multimedia content encoded as output of the Codec, even if that Code
is integrated into a Larger Work.

Permission is granted to you to use the Codec for any personal,
non-commercial purpose, and to copy it, alter it and redistribute it,
subject to the following:

1. You may use the Codec (and any Larger Work created by you) to
create Encoded Content, and may use, copy, distribute, display and
transmit that Encoded Content, provided that Encoded Content may not
be used for direct commercialization, without written permission of
Project Mayo.  For the purposes of this License, direct
commercialization includes uses where the Encoded Content is a
primary or substantial product, regardless of the means of revenue
generation (including, but not limited to direct pay, subscription,
and advertising subsidization).  Direct commercialization does not
include personal or promotional use or uses where the Encoded Content
is a peripheral element of a larger product.

2. You may modify your copy or copies of the Codec or any portion of
it, provided that you cause the modified files to carry prominent
notices stating that you changed the files and the date of any such
change.

3. You may copy, distribute, display and transmit the Codec's source
code, in any medium, subject to the following:

a. You conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and give any other recipients of the Codec a copy of this
License along with the Codec.

b. You must cause any Codec that you distribute or publish to be
licensed as a whole at no charge to all third parties under the terms
of this License. However, you may charge a fee for the physical act
of transferring a copy of the Codec, and you may at your option offer
warranty protection in exchange for a fee.

c. In each instance in which you attribute ownership or authorship of
the Codec you will include an acknowledgement in a location viewable
to users of the Codec as follows:  "This product includes software
developed by or derived from software developed by Project Mayo."  In
any event, the origin of the Codec must not be misrepresented; you
must not claim sole authorship in the Codec.

d. Each time you redistribute the Codec, the recipient automatically
receives a license from Project Mayo to copy, distribute or modify
the Codec subject to these terms and conditions.  You may not impose
any further restrictions on the recipients' exercise of the rights
granted herein.

4. You may copy and distribute the Codec in object code or executable
form under the terms of Sections 3, provided that you also accompany
it with the complete machine-readable source code, or information
about where the source code can be obtained.

5. You may incorporate the Codec into a Larger Work and distribute
that Larger Work under terms of your choice, provided that:

a. The terms permit modification of the work for the customer's own
use and reverse engineering for debugging such modifications.

b. The terms are consistent with the limitations on use described in
Section 1.

c. You include an acknowledgement in a location viewable to users of
a distribution of a Larger Work as follows:  "This product includes
software developed by or derived from software developed by Project
Mayo."

6. Any Codec or Larger Works created by you must conform to the
MPEG-4 Video Standard.

7. You must receive prior express written permission from Project
Mayo before you use the names "DivX;-)", "DivX" or "Project Mayo" (or
any names incorporating those names) or the file extensions ".divx"
or ".div" to promote or endorse products derived from the Codec,
including, but not limited to Larger Works.

8. The Codec contains copyrighted materials that are proprietary to
Project Mayo, and no rights are granted to you except as expressly
provided herein.  You may not copy, modify, sublicense, display,
distribute or transmit the Codec except as expressly provided under
this License.  Any act or attempt to copy, modify, sublicense,
display, distribute or transmit the Codec other than as permitted
herein will automatically terminate your rights under this License. 
However, parties who have received copies from you under this License
will not have their licenses terminated so long as such parties
remain in full compliance.

THIS CODEC IS PROVIDED BY PROJECT MAYO AND ITS CONTRIBUTORS "AS IS"
AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO
THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE AND NON-INFRINGEMENT ARE DISCLAIMED.  IN NO EVENT SHALL
PROJECT MAYO OR ITS CONTRIBUTORS BE HELD LIABLE FOR ANY DIRECT,
INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES
(INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR
SERVICES, LOSS OF USE, DATA OR PROFITS; OR BUSINESS INTERRUPTION)
HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY WHETHER IN CONTRACT,
STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING
IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE
POSSIBILITY OF SUCH DAMAGE.

Thanks in advance.
