How To Read Volume ID from DVD

[m <maglyx@gmail.com>]

There's various places that discuss burning with growisofs and
specifying a volume ID, like
  $ growisofs -Z /dev/dvdrw1  -R -J -V volly tmp/
but although it seems absurd I can't find any way to read this volume
label back once written.

volname is discussed but is worthless here:
 $ volname /dev/dvdrw1
 CDROM

dvd+rw-mediainfo gives other info but not the volume label.

Putting the produced DVD into a Windows machine shows the volume
label, no problem.

Is there any way to do this under Linux?
