Kodi and Digital TV viewer

Hi Folks! First post to this list - I'm a long time Debian user who wanted to try out the latest Gnome-Shell. I've got everything I want/need installed, bar the two applications mentioned in my subject line. How does one get these via repo? Also another question if I may - what is the default package manager for Fedora. I have 4 software mgrs: "Software", Package Manager, Yum Extender and Yum Extender-DNF. What's the difference between the 2 Yum Mgrs? Thanks. If this is the wrong list, please let me know.
