It's not an open source license. Term #6 places limitations on distributing
modified copies. The license attempts to place restrictions on actions
beyond the scope of copyright via a clickwrap/shrinkwrap/implicit acceptance
mechanism. Additionaly, it attempts to discriminate against use by persons
engaged in certain fields of endeavor.

If term #6 were changed to read that non-conforming implementations could
not be distributed if they were called DivX, striking the words USING and
MODIFYING from the acceptance paragraph, and striking the words "personal"
and "non-commercial" from the acceptance paragraph, we would be closer to an
acceptable license.
