This is what i looked at:

http://media.ndr.de/progressive/2016/1115/TV-20161115-0956-4700.hd.mp4

In single step in both mplayer and vlc it shows new frame only every

Looking at the above URL (which i got from MediathekView, it does not
look as if MV did munge everything. this is non-HLS origin material
from broadcaster).
