My 55 inch smart Roku tv works GREAT yes but when I watch AT&T tv now app or Hulu app I will get a weird kind of pixelation or like blowing up then the screen goes back to normal this happens only seldomly yes but if there is a fix for this please let me know I have tried every basic move and step there is to try. Only with the AT&T tv now or Hulu apps. Philo works 100%, all other live tv apps will work 100% except for AT&T tv now and Hulu but also no buffering.
