Please update libmpeg3 to 1.8 version

This is true, libmpeg3 1.7 has been available since July 2006, currently libmpeg3 1.5.4-5 is in the repo for gutsy

Hint: 1.7 changes the API, so it would be necessary to see whether any dependencies are affected.

This bug was fixed in the package libmpeg3 - 1.8.dfsg-2

---------------
libmpeg3 (1.8.dfsg-2) unstable; urgency=low

  * Add patch header-comment-fix.patch to fix a typo in the
    mpeg3protos.h header.
  * Move header files to /usr/include/mpeg3/ to group them together and
    become compatible with Fedora which already place them there. Adjust
    pkg-config file to reflect the change.
