Also, I wrote above that Pronto Hex doesn't allow unmodulated signals. That's not right. If the first 4 digits are 0100 instead of 0000, the output should be unmodulated, if the controller accepts the 0100 format.
I just attempted to to paste modulated and unmodulated versions of the same Sony code to see the differences you report but I realized that the unmodulated codes could not be represented in hex form with the RTI IR library manager where I had the codes stored. I have used them many times but I guess I have never sought to look at the hex window.
