Very interesting that the German customs authority (called Zoll) uses the VLC Media Player for Pr0n screening:
Source from German television (in German): http://www.spiegel.de/video/video-38094.html (last quarter)
It is a little bit funny because it is not so clear if VLC is considered legal in Germany, since it reads DVDs circumventing the copy protection, which is not allowed anymore here.
