Excuse my surprise but which part of "READ DISC INFORMATION" don't you find in MMC-5 6.22 READ DISC INFORMATION Command ? (That's the one with Operation Code 0x51 which cdrecord reports in its "CDB" message.) One does not even have to read the source of dvd+rw-mediainfo to see that its output is organized by SCSI commands and reports the typical keywords from SCSI specs. Nevertheless one can learn a lot from studying the operations of dvd+rw-tools and looking them up in the SCSI specs.
