Zattoo has finally released the linux version of its player.
Unfortunately, only a ".deb" file for Ubuntu is currently available.
But don't worry, it works well on Fedora too!
First, grab the debian package from the Zattoo website: http://zattoo.com/en/download/linux?download=1&version=Linux-i386-deb
Then, extract the files we are interested in with the following command:
ar p zattoo-4.0.4-i386.deb data.tar.gz | tar zx
It will create a "usr" folder, just copy its content to your /usr folder:
cp usr/* /usr/
Then you can start Zattoo Player 4 on Fedora just typing Zattoo from your terminal!
