The Samsung Galaxy tab 2 10.1 is a Tegra 2 device, which won't run Kodi 14.x, so you won't be able to use this addon. For your Fire TV, try the ARM version for Android. You may want to test out a different PVR client (like "Simple") to see if there are any issues with a non NFPS playlist, which will tell you if its your Kodi, or device, vs. the addon.
