I'm struggling to get my new AppleTV 4k to play nice with my Pronto 9400... yes I know its old.

I tried the reverse learning procedure described above- just using the codes that work with my current generation AppleTV- It was happy with up arrow, but complained about down arrow (said its already used...).

I'd like to try what Ranger did- replace play/pause with proper codes...

Would anyone have these codes in a format Pronto would accept or that I could somehow convert?

Thanks...
