I believe this is an error, but didn't find the time to overwork the
debian/copyright files and request their promotion. They are all GPL
licensed packages that should be perfectly acceptable license-wise for

That was btw the main reason I've asked for your concerns. I understand
that there are actually none.

I suspected that, but this has nothing to do with software licenses.

AFAIUI, vlc loads libavcodec.so at runtime via
/usr/lib/vlc/plugins/codec/libavcodec_plugin.so, similar to xine which
kubuntu currently uses. The major difference is that for xine, the
'avcodec' plugin is in the package 'libxine1-ffmpeg', which is
blacklisted on the CDs as well. I'm pretty sure that something similar
could be arranged for vlc as well. We haven't done that yet because
there is (was) no technical necessity for this.

All in all, this all sounds like a realistically solvable problem to me.
