I am experiencing the same thing. The audio will keep running but the picture slows down into slow-mo and its gets choppy....thought it was the app at first...but then I started thinking it was my phone. Haven't figured out a fix yet
Bringing back an old thread. I'm experiencing really bad choppy video not only in Netflix, but in other apps where the software delays fir a split second before responding. I downloaded No Frills CPU Control and just set the governor to Performance. Now everything is running smoothly again!
