Daniel, the Pronto Hex you posted is NEC1 device 49.0 function 160. Power toggle should be NEC1 device 49 (or equivalently 49.206) function 91. That's completely standard for these Sanyo VCRs, and the learn posted by 98CarmineRedTN decodes as that-- only the ditto part is incorrect. Here's Power toggle with the ditto part rendered correctly:
0000 006C 0022 0002 015B 00AD 0016 0041 0016 0016 0016 0016 0016 0016 0016 0041 0016 0041 0016 0016 0016 0016 0016 0016 0016 0041 0016 0041 0016 0041 0016 0016 0016 0016 0016 0041 0016 0041 0016 0041 0016 0041 0016 0016 0016 0041 0016 0041 0016 0016 0016 0041 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 05F7 015B 0057 0016 0E6C
If the intent was to try NEC 1 device 49, function 160, then:
0000 006C 0022 0002 015B 00AD 0016 0041 0016 0016 0016 0016 0016 0016 0016 0041 0016 0041 0016 0016 0016 0016 0016 0016 0016 0041 0016 0041 0016 0041 0016 0016 0016 0016 0016 0041 0016 0041 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0041 0016 0016 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0041 0016 0016 0016 0041 0016 0016 0016 05F7 015B 0057 0016 0E6C
There probably isn't any discrete code for power in this VCR. But you can search for it, using various function numbers with device 49. I recommend
IrMaster instead of MakeHex, because IrMaster can both encode and decode Pronto Hex, and has a bigger library of IR protocols. It is under active development. In this case, after rendering the Pronto Hex, the decode could be immediately checked to see that the parameters were entered correctly
