I have a #RokuExpress I just got two weeks ago. It randomly reatarts. I can sometimes get through an entire movie or TV episode, but most times it will randomly restart within a few minutes. I've tried a different TV, different cables, plugged the USB directly into the TV, different power bricks, etc
It's very frustrating, and frankly, makes me want to send it back and ditch Roku altogether. Is the fire stick any better? Guess I will find out ...
