Actually cdrecord is not involved as it does not support dvd+rw.
growisofs launches mkisofs and uses dd somehow to send the data to the
drive. I have just discovered that you can do 'growisofs -Z
/dev/sr0=/dev/fd/0' and pipe the mkisofs output into it though, so the
same idea applies. I think I'll give that a shot as I don't think that
buffer underruns are the source of my problem.
