Hello
I think ordner, if it isnt a typo might be ordinateur, which would be french for computer.
By default it is not possible to just watch stuff on your mycloud without first downloading the whole video, through the android app, for example. Which is pretty ■■■■ in 2016 but at least I didn’t buy the thing expecting that functionality.
It can be enabled with via webdav, but it will probably only work if you have really decent internet (which i do not).
some useful info i had saved in a text file about how to get it up and running and a config file which actually works (seem to recall none of the http config i was able to find at the time I was getting it working actually worked):
