Depending on the reason(s) why Ubuntu won't put avcodec and avformat to gold,
someone should check whether other codec libraries are acceptable, notably
libmpeg2, liba52 and libdca. If not, some more VLC plugins will need to be
relocated, and some more plugins will be OK but useless. This will reduce the
set of currently non-main dependencies.
Also, dvdread and dvdnav are not terribly useful as there are not too many
cleartext DVDs out there.

This will render the player mostly useless, playing mostly Theora and Dirac
(not even WebM - it uses avcodec). I don't know how this compares to the
feature set of the current stripped xine-lib. But I am a bit afraid that this
will give a terrible first impression to many users, especially those knowing
VLC as the solution to Windows codecs hell.
If it were me, I would have the user install a proper codec-rich player (Xine,
VLC, mplayer or whatever you like) from the online repositories in the most
obvious and seamless manner instead. But it's your call anyway.
