Hmm, I haven't had any issues but I don't use any torrents with it so maybe that's why.
Late pass, but I never bothered anything fancy with my Fire Stick. I bought one when they first came out and they were on sale, it's been a solid bedroom TV box that I use to watch Netflix. But I just realized the other day "Oh, I should see if I could install Localcast on it" and sure enough there was an Amazon app for it. Worked perfectly just like on the Chromecast so that's a good option if I wanted to stream from Movie HD or Showbox.
