I am trying to copy the Source button from the Rio remote to my Pronto. As this button works as a source switch with a short press and as the power switch with the long press, I wish to be able to send the long press so I can turn the Rio off(standby). I haven't been able to get this to work yet. When I "teach" the Pronto the source button it doesn't matter if I hold the button on the Rio long or short. It is learned as a short press and will only switch sources on the Rio. I'm sure that there is some hex code I could edit into the button code if I only knew what it was. The button codes as they come up in hijack don't look anything like the learned codes in the Pronto. I don't think this is unusual but it does make it more difficult to determine what is the correct code to enter to produce the results I'm looking for.
