Thanks therefore much, Ed (@tivoburkee) hopefully yourself having some trick up your sleeve!

Apologize but when it comes Jensen watching few own had so loads different code sets its not witty, its an new code each time a new model comes out, its like they buy off unsold models the stick the jenssen name on itp. I would got a universal remote with learning performance so you sack it the commands from the Jensen remote. Thats if thy roku accepts INFRARED commands. 

Thanks so lots for the reply. I just called Roku and got the rush round still you answered it directly. I'm using a video stick, I noticed ensure most regarding the remotes I'm finding online does not working with the streaming sticks, only the roku TV's or cases. Can I just assume I'm stuck with two remotes at this point?  There is no learning function, inspect function, or known compatibility are other brands?

You can try moving into the secret menu and switching to hdmi-cec instead of IR, that's if your tv does that feature;

Home 5x, PP, PG, RW, PP, FF  /RF Remote Menu  /IR Transmit Menu

PP the play/pause

If it works it wants be wifi amongst that remote and the roku stick+, then it would be cec across the hdmi connector to the tv. None IR involved. 

Thanks, none such destiny how the CABLE doesn’t sales CEC. It did turn off still the volume didn’t respond. That your stranger is I’m had trouble with my new roku streaking stick advantage EGO just purchased at Best Buy but my older roku streaming stick remote controls my same Jensen TELEVISION no problem. Apparently the younger remove has less compatible. Is there a way to update the remote rules?

I was up with the same issue about my Jensen TV and new Roku remote.  The new shiny awesome Roku remote was not compatible and my old dog-chewed scratched up Roc got no issues for my Jensen TV.  Looks like Rod took a shortcuts in their programming of their remotes.  Maybe I can find some old spare remotes set EBay since my old Roku remote is held together equipped scotch tape. 🥴
