Kodi MythTV PVR automated packages from rpmfusion. and unitedrpms. sadly haven't been working on my Fedora 24 or 25 systems for quite sometime with crashes and failures to load that I couldnt figure out easily.
I've manually built the addon using the following commands (on a 64bit Fedora 25 system) for Kodi 17.0 (krypton). Tested working on a few Fedora 24 and 25 systems here. :)

git clone -b Krypton https://github.com/xbmc/xbmc.git
cd xbmc/project/
git clone -b Krypton https://github.com/kodi-pvr/pvr.mythtv.git
cd pvr.mythtv && mkdir build && cd build
cmake -DADDONS_TO_BUILD=pvr.mythtv -DADDON_SRC_PREFIX=../.. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../../../addons -DPACKAGE_ZIP=1 ../../../project/cmake/addons
cp pvr.mythtv-prefix/src/pvr.mythtv-build/pvr.mythtv.so ../pvr.mythtv/
cd ..
zip -r pvr.mythtv.zip pvr.mythtv

You can either manually do the above to build it yourself of try my build (v4.12.7) [here]. Hopefully saves someone else 2 mins :)
