How do I verify the MD5 of my burnt DVD?


From my WinXP machine:
I have downloaded SUSE-10.0-EvalDVD-i386-GM.iso and the MD5 sum.
Using MD5 Summer I verified that the ISO was ok

Using Nero 7, I have burnt the image to DVD and used the "verify option". Nero reported everything ok.

I can boot from the DVD and I did a media check, again "no errors".

I then used IsoBuster to create an MD5 from my burnt DVD and it doesn't match the ISO MD5. After some research I gather that the two MD5's might be different (?)

So, how do I verify my burnt DVD against the ISO MD5?
or is there anything else I can do to check I burnt the ISO correctly?

Thanks, Ilija

Edit: doh! wrong distro forum but anyway...

I use the following script (saved as to get data from a CD or DVD so that I can burn or check md5sums:
# See <>
# Reads directly from the CD or DVD device specified on the command line amd dumps it to STDOUT
# Typical usage:
#       /dev/dvd > /tmp/dvd-contents.iso
# To use this script to check the md5sum of the disk, do the following:
#       /dev/dvd | md5sum
#   compare the result with:
#                md5sum /tmp/dvd-contents.iso
# Burn the iso with something like:
#                /usr/bin/cdrecord dev=ATA:1,1,0 speed=10 padsize=63s -pad -dao -v -eject /tmp/dvd-contents.iso


blocksize=`/usr/bin/isoinfo -d -i $device | grep "^Logical block size is:" | cut -d " " -f 5`
if test "$blocksize" = ""; then
	echo catdevice FATAL ERROR: Blank blocksize >&2

blockcount=`/usr/bin/isoinfo -d -i $device | grep "^Volume size is:" | cut -d " " -f 4`
if test "$blockcount" = ""; then
	echo catdevice FATAL ERROR: Blank blockcount >&2

command="/bin/dd if=$device bs=$blocksize count=$blockcount conv=notrunc,noerror"
echo "$command" >&2

# ends.
