Beg to differ on that point I have a 1st Gen Firestick using SMART IPTV Player and get no problems at all,when I first used this as a means for iptv I was told to get rid of every app as this only slowed it down and Kodi was nearly almost the reason for this I turned off all app notifications and regularly clear data and cache from the amazon ones that cannot be deleted and enjoy nearly faultless playback yes I get the rare glitch now and again but not constant buffering as TJF2801 is experiencing,speed and server would be a good place to look
