The library of BR improved in the user interface constantly - also use this app for the Amazon Fire TV stick. The app I have installed on the Fire-TV-Stick. Unfortunately jerky transmission - obviously buffer problems or other problems. I have the Fire TV stick with Smart TV and with Raspberry PI 2 B on the same TV compared (BR) - also with an Android system (Tablet PC) - in the same home network. The APP BR Video library is not to be used on the Fire-TV-Stick, as about every 30 seconds, sometimes even less the stream is and recharging starts. My criticism is not directed against the user guidance. As long as the stream does not run I will spare me further comments. Amazon is doing a disservice to it, - if such shortcomings occur. The advertisement promises more here. Product matures at the customer. The Amazon has this necessary is incomprehensible for me. Interestingly, the YouTube app runs on the Fire-TV without any problems - apparently better implemented or optimized.
