</I>
The problem is that that "balance" was achieved by sticking packages in
PLF/main/contrib semi-randomly. For example, H.264 decoders and MPEG-4
video encoders are in main/core, while e.g. AAC audio decoders are in
PLF/tainted. If one'd put them into an order, IMO H.264 and MPEG-4 would
be much more prominent and tainted candidates instead of AAC decoding...
Also, in e.g. MPEG-4 case we have encoders both in core and in tainted,
e.g. we have ffmpeg in core, but xvid in tainted.

</I>
Linux Mint provides a "No codecs" CD:
<A HREF="http://www.linuxmint.com/download.php">http://www.linuxmint.com/download.php</A>
Ubuntu has a patent policy (which basically IIRC says "rights owner or
packager, please contact us if you think there is an infringement, we
will investgate"):
<A HREF="https://wiki.ubuntu.com/PatentPolicy">https://wiki.ubuntu.com/PatentPolicy</A>
Note also that the Ubuntu Live CD and therefore the default Ubuntu
installation do not contain any codecs. By default Totem is installed,
however, and gstreamer is plugged into "gnome-codec-install" (which
seems really nice, do we use it?), so that wen you try to play an
unsupported video the first time, it will prompt to install the codecs
(it will also show a warning dialog about patents etc, but AFAICS this
comes from gnome-codec-install itself, not Ubuntu).
If the user installs a video player depending on ffmpeg, e.g. VLC via
the software center, the codecs in ffmpeg will be pulled "normally",
i.e. silently.
Linux Mint had also gstreamer plugged to gnome-codec-install, so the
codecs will be installed if the user tries to play such a video with
totem (again with warnings).
