Once or twice a week an app will perform poorly until after a reboot of the Mini. This happens with all of the apps I use: Netflix, Amazon Video, Vudu, HBO GO & Epix. I don't think this has been happening with the TiVo XL master as my kid has not complained about it, but I haven't used that one directly in so long I can't be sure. The problem presents as slow navigation and shows/movies will act as if they are buffering. Sometimes it's only slow enough to be annoying. Other times the apps are unusable. A reboot ALWAYS resets to normal.
