I've pasted each of your codes into PPENG, but I've noticed that as soon as I switch to a different button to do the next one, when I go back, PPENG has changed the codes!
This is what PPENG seems to 'translate' each of your codes into:
Why does this happen? Does PPENG somehow validate or parse the codes to a particular format?
Regardless, I've tried using the 'Test IR' button immediatley after pasting (while I can still see your code in the window), and saving each button (so that PPENG changes it to the above) and downloading it to the Pronto - still, none of the codes work!
