mmc5r03c.pdf 5.3.16 , table 127 specifies that mode page 5
shall be supported with feature 0026h Restricted Overwrite.
5.3.22 describes a feature 002Ch Rigid Restrictive Overwrite
which seems to apply to DVD-RW and does not mention page 5.
5.4.14 finally states that profile 0013h includes feature
002Ch rather than 0026h.
