Looking for suggestions / recomendations

I was going to use plex for my home media setup because i really like its simplicity. After all i have to have this user friendly for my wife and kids. However have found 1 really terrible flaw, plex does not have any real support for the hd homerun prime. There are some unsupported plugins and i was able to get it going but its interface was not great and there was no tv guide at all.
I have been playing with kodi for about a month now and i really like it other than the silly fact amazon doesnt allow you to just download it and install it from their version of a play store ( silly pirates ruin a great media platform )
I have decided a centralized system to manage things will be the way to go, especially with how cheap and powerful a resberry pi 3 is. So i am making that little thing the heart of the media center with 1 fire tv and later a fire stick or maybe a fire tv
So my question really is this, what is a good setup for kodi to work with a hd homerun prime and is it possible to have dvr functionality? It would be especially awesome if someone knows about drm channels so i could watch hbo also right from kodi.
Essentially i am trying to make a home media setup where i can manage all the movies in 1 location so the cover art and everything shows up properly on all the devices once i have it correct on the media center.

Thank you!
