Okay spoke too soon. Method 3 just doesn't change any inputs. When I added an older Nintendo for my son on AV1 composite, it won't change the inputs. So back to square one. Even though the harmony shows discrete codes for the 3 hdmi inputs, it doesn't actually do anything but cycle through the inputs. Any other ideas? If I pay for support from Harmony, do you think they could solve my issue?
Thanks again for the reply.
