I have the same issue with my Ultra remote. When I hit the arrow keys or when I press FF, it kicks me out of whatever app I am in and wants to open Hulu!!! I don't even have a Hulu subscription. Something in the remote buttons is clearly crossed-up randomly. And no, I'm not hitting the "Hulu" button my accident, before anyone says that. This is only happening with my Ultra remote. I also have a Roku TV and a Roku Stick on my garage set and those remotes never do this.
That's our Roku number. Those two "O"s might be zeros, but I think they are "o"s. The remote buttons frequently will act as if you pushed one button when you actually pushed another. It's very frustrating - like the wires are mixed up or shorting inside. I really don't know. But like I mentioned before, it didn't happen with our other two Roku devices/remotes. Just the Ultra.
YJ00AD613011 - Same as the other poster, not sure if those are zeros or "O". Hard to tell on the screen. Still having the same issue as my original post - crazy remote randomly kicks me out of whatever I am in, and tries to start "Hulu", no matter what buttons I press!
