We don't have enough test media to be 100% confident, but it appears that the media with ID "VERBAT/IMk" will not work with older firmware releases in the Pioneer drive, but that media with IDs "TDKBLD/RNC" and "VAMKM/IMk" will work in drives with either firmware versions.
The following is from a CLI test on a piece of new, blank media placed into two drives with earlier and newer firmware.
