re: Nope. I have a Roku 1.
Then I have no idea how you can see a Youtube app in the Channel Store and I can’t. Are you sure you didn’t get the private channel hack that was available back in 2010 before it was withdrawn at Youtube’s demand?
I didn’t get my Roku until early this year, it was brand-new, I took it out of the box, plugged it in, and haven’t touched it since. You Tube was just available.
