Cannot watch ARTE media center videos (youtube works): do i need some packman packages?

I have the current opensuse Tumbleweed installed on my notebook, only default repositories, no packman.
I can watch youtube videos but i cannot watch videos from the Arte (a french/german tv station) Mediathek/media center (like this:! The error message is very simple, it basically just says that my system does not fulfill the needed (system) requirements.

But i guess that there is just some package needed that only packman can provide, can anyone confirm this?

Watching ths video works for me on my hardware from 2005 (i686, ATI gfx).
But I have installed lots of packman packages.


Thanks, i followed the instructions and now i can watch the videos.
