Some members may not be aware that the latest STB Emulator Pro version 1.1.1.4 makes a huge impact on freezing issues but you should check to make sure your STB Emulator Update has all the boxes checked in its Settings. I did 3 updates today and the latest one really brings the buffering and freezing to almost non existent. Many know that there are several servers that come up in Kodi 17.6 when using addons. If one server doesn't provide a smooth picture, Stop and return to the menu and select a different server until you get a smooth picture without freezing or buffering. Only real complaint I have is the pairing up that usually brings my interest to a halt. Too much trouble and not worth the time especially when the server is HD and it doesn't provide a clear picture. Anyway, be sure to keep updating and avoid using an older version.
