And, it's interesting to note here, growisofs is now calling "DVD+RW format"?

$ growisofs -dvd-compat -Z /dev/dvdrw=/tmp/tmp.iso
Executing 'builtin_dd if=/tmp/tmp.iso of=/dev/dvdrw obs=32k seek=0'
/dev/dvdrw: restarting DVD+RW format...
/dev/dvdrw: "Current Write Speed" is 2.5x1352KBps.
builtin_dd: 1632*2KB out @ average 0.8x1352KBps
/dev/dvdrw: flushing cache
/dev/dvdrw: writing lead-out
/dev/dvdrw: reloading tray


I'm pretty sure this DVD+RW disc is an official coaster now.
