Comment 12 for bug 660807

I just backed down to (U)OOo 3.2.0 (purged all 3.2.1) on the same system:
$ apt-cache policy openoffice.org
openoffice.org:
  Installed: 1:3.2.0-7ubuntu4.1
  Candidate: 1:3.2.0-7ubuntu4.1
  Version table:
 *** 1:3.2.0-7ubuntu4.1 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/universe Packages
        500 http://security.ubuntu.com/ubuntu/ lucid-security/universe Packages
        100 /var/lib/dpkg/status
     1:3.2.0-7ubuntu4 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/universe Packages

Opening and playing the .avi in a new Impress presentation works w/o issue. So the problem is a regression between (U)OOo 3.2.0 and (U)OOo 3.2.1.
