Added more info about DVD+RW

 there is no difference between -sao and -tao. If ever, then -tao will be the
 mode which preserves the current behavior.
 
+For DVD+RW, -msinfo alone would not be enough to perform appending of an ISO
+filesystem. The filesystem driver will need a hint to find the start of the
+most recent session. For example put an ISO filesystem at address 1 GB:
+  mkisofs -C 0,524288 ... | \
+  cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
+The superuser may then do:
+  mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
+Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MB).
+To extend a filesystem already existing at address 0
+  mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
+Record the number 524288 for usage as first number with -C at the next
+extension:
+  mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
+
+Program growisofs can append to an ISO filesystem on DVD+RW by additionally
+manipulating the first session. cdrskin does not want to get involved so deep
+into the format of the burned data. Be advised to use growisofs for the
+task of maintaining extendable ISO-Filesystems on DVD+RW.
