You can't achieve all this at once with growisofs. What you look for is live read-write file system on DVD+RW, which requires kernel support. Unfortunately not all DVD+capable units are capable to sustain true random I/O, see http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00015.html and follow-ups. There was work done to compensate for deficient firmwares, see http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00061.html. But public consensus seem to be it's too slow to be practical.
