Thank you, folks. Have it working. Low end remote does have IR port, it simply takes close look to notice, as it's blanded into entire front of the remote.
Also, it works with high end Roku, but I had to get 2 feet away from it. Thereafter, I could back away from it and it kept working. I think, it simply had to "learn" IR remote, as there was a moment of hesitance in responce, then it was all good.
Also, finished setting up my learning remote - and it also works. The only button I can not set up is Home, but it's ok.
Once again - thank you. It's still a 4 step dance, as I have to switch between remote modes to get to volume, but it's better than carrying 2 remotes.
