I have a similar and probably related problem so I will describe it here
and not create another bug in the hope it will help the devs pinpoint
the causes.
I recently upgraded a server from dapper to hardy after which my DVD-R
burning archive script starting failing.
The script for dapper ran overnight, used mkisofs and worked a treat.
The script was designed for non-computer people - they would
periodically put a blank DVD-R in the drive in the evening. The return
code from mkisofs was detected by the script. If the mkisofs run
succeeded (that is, a blank disk had been inserted the previous
evening), the script ejected it ready to be removed and filed the next
day. If it failed, the script presumed it was because no media had been
loaded and failed quietly.
The script needed to be changed for hardy - mkisofs was replaced by
growisofs. I overcame bug 233942 by replacing genisoimage 1.1.6-1ubuntu6
with genisoimage 1.1.6-1ubuntu3. However, there are clearly still some
other problems with DVD burning on hardy. Here are some of the symptoms
I see:
1. The growisofs/genisoimage relationship does not seem quite right. An eject
command after the growisofs command appears to be executed before genisoimage
terminates. Indeed it seems to execute almost before genisoimage starts. See my
thread here:
http://ubuntuforums.org/showthread.php?t=963701
2. growisofs always seems to return zero.
3.. If I run the archive script manually after loading a blank DVD-R, it
creates a legitimate burned disk which I can read successfully if
removed from the drive at that point.
4. If the script is run via cron overnight, I believe the disk is OK
just as the result from 2. above is. Here are the key parts of the log
which is emailed to me:

However, if the disk is left in the drive and the script runs 24 hours
later on the same disk, it appears to try to burn the disk again (and I
think it partially succeeds - see below) but fails as follows:
Executing 'genisoimage -r -J -joliet-long -V othona011108 -ldots /home/core/My

What is very strange is if the DVD-R is examined in daylight, the
originally burned (dark) circular area is visible but superimposed on it
is a smaller circular area which is even darker as if that smaller
central area has been burned again. After the second run, the DVD-R is
not loadable or readable on any Linux or Windows system.
5. I have another recently-upgraded-from-dapper-to-hardy server which
uses the same script to burn archive CD-Rs (note *not* DVD-Rs) and it
does not have the double burning problem described above. I think it
does however also have the eject-before-burning-complete problem.
I too have concerns about how this problem can remain
undiagnosed/unfixed for so long. growisofs appears to behave quite
differently to the original mkisofs - it is a pity that there was not a
transition period where both were available so that mkisofs could be
used in situations where growisofs did not work properly.
