So, after installing vlc-nox/lenny and upgrading to sid:

-> trying to upgrade just vlc-nox:
parapide-16:~# apt-get install vlc-nox

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  vlc-nox: Depends: libavformat52 (>= 4:0.5.1-1) but 0.svn20080206-18+lenny1 is to be installed or
                    libavformat-extra-52 (>= 4:0.5.1-1) but it is not installable
E: Broken packages

-> trying to upgrade vlc-nox, forcing installation of libavformat-extra-52:
parapide-16:~# apt-get install vlc-nox libavformat-extra-52
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libavformat-extra-52 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package libavformat-extra-52 has no installation candidate

-> trying to upgrade vlc-nox, forcing installation of libavformat52:
parapide-16:~# apt-get -y install vlc-nox libavformat52

=> so that works, but why doesn't apt-get figures it out by itself?
(it might be an apt bug rather than a vlc-nox one)
