Interesting read. How do you get to this on the H20 or HR20, it looks neat but I can't find it:

Go to any of the interactive channels.
After a few minutes it will prompt you to hit the RED button.

HR20 only, the H20 is not interactive yet.
(R15, D10, D11 will work)

So, are all the interactive channels based on the 'active' channel? Are there other channels that are interactive?

Mix channels.
102, 103, 104...
