I am reading the users' manual I got with my Insignia.Roku ready TV. It shows that I should be able to use the Insignia remote for Roku. I find that I can only turn the TV on, off, mute it, and turn the sound up and down. None of the other buttons indicated in the manual will work.
It is tedious to switch between remotes if I don't have to. I use the Insignia remote for broadcast channels and would like to use it for Roku also.
