These two Pronto Hex are effectively the same, and both decode to Denon IR protocol, device 4, function 135. For at least some Denon receivers, that would command "Matrix". Is Matrix the function you have in mind? And does your receiver support it?
Denon Tech Support gave me the code and told me it will work for my AVR3300. My receiver has a DSP button that navigates through five different sound settings. One of them is Matrix.
