Installing the package `vlc` manually fixes the problem and I can play
the videos just fine.

So `vlc-nox` was installed already due to the package `k3b`. Does
`vlc-nox` provide `vlc` in any way? I only could find

    Replaces: vlc (< 1.1.0)

which should not have to do anything with it, right?

So, I would make this bug about the problem, that `vlc` is not
installed, when `vlc-nox` is already installed.

Looking at the recommends again, I see `mplayer` in there. I also have
the MPlayer package installed. Might that be the reason?

Then the bug is about, that when `vlc-nox` and `mplayer` is installed,
mediatheview does not use MPlayer but VLC. Then this bug should be
reassigned to mediathekview.

Some solutions might be, to try MPlayer before VLC by default or just
recommend the package `vlc` and demote `mplayer` and `mplayer2` as
suggests(?), so mediathekview works out of the box.


Thanks,

Paul
