well the folks have made a mess post their ideological flame war with Joerg Schilling over cdrecord and we have this thing called 'wodim'
The command goes thus:
#wodim -eject -sao -v speed=2 dev=/dev/cdrw FreeBSD-11.0-CURRENT-amd64-20140308-r262915-disc1.iso
the general listed options like wodim -scanbus etc donot work !
Hope it helps people.
