One way to get the original data is to use [Link: awe-europe.com].  The BDS1067 are the newest Blu-Ray codes they have.  The upgrades section at hifi-remote.com also has Yamaha Blu-rays, and those can be read using RemoteMaster.

The Yamaha converter has to be used carefully.  In this case the Yamaha documentation tells us that Power On is Custom code 7C and Data0 is F6.  That's actually short hand for Custom code 7C83 and Data F609, where 7C and 83 are the binary complement of each other, as is F6 and 09.  The Yamaha spreadsheet displays the 09 in greyed out font.

The correct entries into the Yamaha converter are either 7C F6 or 7C F609 or 7C83 F6 or 7C83 F609, where the space distinguishes the custom code (usually called the device number) from the data (usually termed the function number or OBC). Evidently whoever generated the codes hdtvlvr has posted instead entered 7CF6 09, which produced device 124.246 with OBC 9.

I like to use the import function in IRScope to check Pronto Hex, because it can show the waferform graphically, and export clean versions of learned Pronto Hex.  There is a newer version of DecodeIR.dll (2.43) available, and you should download that also.
