You are incorrect, or mis-understod. I am enabling the developer installer page on the player using the remote keys.
I finally got it to show up by moving to one of the other channels (not settings) at the top level and then doing the debug display and then the developer enable key combo. I'm not sure how important all of that was, but I tried it from various other places in the UI without it working.
I'm looking forward to playing with this! Thanks to Roku for releasing this!
