Didn't correctly add from the catalogue, added "RX-V38" and no commands would work. Was able to add via IR blast testing codes.
However:
List of available codes doesn't include "Next/Prev Input" so I had to learn from original remote. "Prev input" refuses to learn despite saying it is successful. Next input does work though I'd rather not have to cycle through a dozen input when I should be able to do it in one button press.
Please advise thanks.
