The lirc codes are all Sony20 26.241. The learned Pronto Hex has 2 complete Sony20 26.241 signals, function 45 (S in the LIRC file). That is followed by a Sony20 26.241 signal in which the function bits are ill-formed, with shorter than expected On durations. That's followed by two more signals, in which the On pulses are just a short burst. All of these however have the same basic timing as a Sony20 signal, and would correspond to function 45. I suspect weak batteries. You can see this by importing the Pronto Hex into
IRScope, setting the graphical display to 25uSec per pixel, and setting the window width so each of the 5 signals starts at the left edge.
The LIRC decodes to Sony20 26.241 with the following function numbers. I recommend
IrMaster to generate the Pronto Hex, although MakeHex will work for Sony20.
