I own a vizio tv and loved the idea of the co star because it also claims its a universal tv remote. I hooked it up paired the remote with the tv so the volume went up. And the. Switched the tv back to normal tv (cable) and when I do this only the volume buttons work I can't change the channel or anything. I don't have a cable box but that said its possible to make the remote work with just normal tv when the co star box is off. How do I do this!?
