I believe the problem is within the directvnow app within the Roku Stik. I just did a side by side comparison with Amazon Firestick and Roku Stik. The Roku Stik only buffers on directv now app and no others. The Amazon firestick never buffers at all. There is some kind of glitch within the directv now app on the Roku. If they would/could resolve this issue, then directv now on Roku would be GREAT!
