 Setting "on" tries to circumvent the management of defects on DVD-RAM, BD-RE,
 or BD-R. Defect management keeps partly damaged media usable. But it reduces
 write speed to half nominal speed even if the media is in perfect shape.
 For the case of flawless media, one may use -stream_recording "on" to get
 full speed. 
+.br
+"full" tries full speed with all write operations, whereas "on" does this
+only above byte address 32s. One may give a number of at least 16s
+in order to set an own address limit.
+.br
+"data" causes full speed to start when superblock and directory entries are
+written and writing of file content blocks begins.
