What steps have you taken to install either addons? Zip files or through a repository? What KODI version have you tried installing on? Minix's or Jarvis etc? Running stock or a custom build, etc.. More info is required..

Still not enough info.. Following steps in a YouTube video... What actual steps? Please list out.. I would also advise you install Jarvis and  mess with that instead.. Restore the pre-installed XBMC for Minix and leave as is, preferably for local media playback.. Both versions can coexist on the same box.

Edit: Here are quick steps to installing Exodus..

1. Install the Fusion repo.
2. After installing.. Install from zip file..
3. Choose the Fusion repo.... Then xbmc-repos.
4. Scroll down and install the Exodus repo.
5. After that's installed, navigate out and back to install from the Exodus repo.
6. Install from repository > Exodus Repository > Video addons... Select Exodus.. Install..
7. Check your video addons after installation..
8. Profit!

Welcome... As for content, in addition to the addons already mentioned here in KODI thread like cCloud or Specto, etc. You can install third party apps like MX Player, Mobdro (TV channels), TV Plus 2.0 (Chinese TV channels), CartoonHD, Popcorntime, Showbox, MoviesHD, etc.
