"mpeg" and "mpeg-3" are just able to decode mpeg-file, which you don't
seem to care about right now.
the funnier parts are quicktime and aviplay; these APIs both support a
number of codecs depending on how they were compiled and/or which codecs
they find on your harddisk.
(i think libquicktime have changed their policy to just include built-in
codecs; whereas aviplay uses external codecs)
so the key thing to do to get more movies to load is to either update
these libraries or install (or update) packages that provide codecs.
on debian, one beloved package used to be "avifile-win32-plugin" from
debian-multimedia-org, which would provide a number of non-free
(potentially copyright and/or patent protected) codecs as w32-dlls.
i don't know whether there is this package for ubuntu (or whether you
can "just use" the debian-multimedia packages)
due to the potentially illegal nature of some codec packages available
in the net, these packages vanish from time to time.
