Hi,
I have tried four times to burn the 'openSUSE-10.2-RC1-DVD-i386.iso' image file to a dvd, and the three times it failed to compare:
growisofs -Z /dev/hdc=openSUSE-10.2-RC1-DVD-i386.iso && sleep 5 && nice ionice -c3 diff /dev/hdc openSUSE-10.2-RC1-DVD-i386.iso ... Executing 'builtin_dd if=openSUSE-10.2-RC1-DVD-i386.iso of=/dev/hdc obs=32k seek=0' ... 3679551488/3696027648 (99.6%) @5.5x, remaining 0:02 RBU 49.1% builtin_dd: 1804704*2KB out @ average 5.1x1385KBps /dev/hdc: flushing cache /dev/hdc: closing track /dev/hdc: closing session
Files /dev/hdc and openSUSE-10.2-RC1-DVD-i386.iso differ
Another try, a slightly different command:
time growisofs -dvd-compat -Z /dev/hdc=openSUSE-10.2-RC1-DVD-i386.iso && sleep 5 && time nice ionice -c3 diff /dev/hdc openSUSE-10.2-RC1-DVD-i386.iso Executing 'builtin_dd if=openSUSE-10.2-RC1-DVD-i386.iso of=/dev/hdc obs=32k seek=0' /dev/hdc: "Current Write Speed" is 16.4x1385KBps. 0/3696027648 ( 0.0%) @0x, remaining ??:?? RBU 100.0% ... builtin_dd: 1804704*2KB out @ average 5.2x1385KBps ... Files /dev/hdc and openSUSE-10.2-RC1-DVD-i386.iso differ
The error is consistent, the md5sums of the four dvds is the same:
cer@nimrodel:/Disco40/dvdiso> nice ionice -c3 md5sum /dev/hdc 5cce82c8cdded4df0d30e78f636d40a4 /dev/hdc cer@nimrodel:/Disco40/dvdiso> nice ionice -c3 md5sum /dev/hdc 5cce82c8cdded4df0d30e78f636d40a4 /dev/hdc cer@nimrodel:/Disco40/dvdiso> nice ionice -c3 md5sum /dev/hdc 5cce82c8cdded4df0d30e78f636d40a4 /dev/hdc cer@nimrodel:/Disco40/dvdiso> nice ionice -c3 md5sum /dev/hdc 5cce82c8cdded4df0d30e78f636d40a4 /dev/hdc
But the md5sum is different from that of the iso image file (which it is the same checksum as the published one):
cer@nimrodel:~> nice ionice -c3 md5sum /Disco40/dvdiso/openSUSE-10.2-RC1-DVD-i386.iso 075ffaa3e2b8037edd2279f95c26ea39 /Disco40/dvdiso/openSUSE-10.2-RC1-DVD-i386.iso
So, there is an error burning the image, but it is consistent. Weird, isn't it?
I have used that same command to burn other images (even an hour before) with no problem but the RC1... no way!
Is it possible that there is something in an iso image that may prevent it from correct burning?

I don't know if this will help, but I just burned the same iso via k3b this morning, and according to its log, the command it used was [Used versions] growisofs: 6.1 [growisofs command:] /usr/bin/growisofs -Z /dev/hdc=/home/joe/iso/openSUSE-10.2-RC1-DVD-i386-iso/openSUSE-10.2-RC1-DVD-i386.iso -use-the-force-luke=notray -use-the-force-luke=tty -dvd-compat -speed=8 -overburn -use-the-force-luke=bufsize:32m [growisofs] Executing 'builtin_dd if=/home/joe/iso/openSUSE-10.2-RC1-DVD-i386-iso/openSUSE-10.2-RC1-DVD-i386.iso of=/dev/hdc obs=32k seek=0' [growisofs] /dev/hdc: "Current Write Speed" is 8.2x1385KBps.
... Executing 'builtin_dd if=openSUSE-10.2-RC1-DVD-i386.iso of=/dev/hdc obs=32k seek=0'
I do know it passed the Media Check. HTH

Yes, the command is very similar. The "use te force things" are used by k3b and not needed for normal comand line use. Speed is not needed, and it is ignored, anyway.
I do know it passed the Media Check. HTH
And mine does as well... yast says it is Ok. Weird.

some clues?
do you use a rw media? did you try to boot the dvd? if it boot, try using the yast test media option if it don't boot, try the test media option in an installed yast
Is it possible that there is something in an iso image that may prevent it from correct burning?
a failure on a part of the medium
I had the same thing with RW cd, I had two failed RW medium on my collection (too old?) - all the others run well.
I also had a pack of new dvd r+ that couldn't write all - they got an error in the burning process (but the result was legible - at least as much as I can see, there are video)

I burned four write-once normal dvds: all are wrong, but equally wrong, all have the same wrong checksum.
I also tried to burn a RW unit, but it failed completely. I can not even reformat it, perhaps it is not compatible wiht my burner. No idea about that one.
The burner is relatively new, two months.
did you try to boot the dvd? if it boot, try using the yast test media option
I haven't yet.
if it don't boot, try the test media option in an installed yast
Didn't know that was possible. Doing it now. You mean yast of 10.1 testing the dvd of 10.2?
Is it possible that there is something in an iso image that may prevent it from correct burning?

But how can four different DVDs have an error in the same way? The errors would be random, they would not have all the same checksum

Three came from the same box that I have burned the other 20 Ok, the fourth from a new box.

Yast says the DVD is correct:
Check started (/dev/hdc)... Identification: openSUSE-10.2-dvd5-download-10.2 Medium: CD1 Size: 3609402 kB Result: OK
Weird and more weird. The checksum says it is incorrect, Yast says it is Ok.. Diff program error reading from device?

I extracted the image from the dvd, and it has a few bytes more (6 kilobytes exactly):
dd if=/dev/hdc of=image.iso
cer@nimrodel:/nuevo/tmp> l /Disco40/dvdiso/openSUSE-10.2-RC1-DVD-i386.iso image.iso - -rw-r--r-- 1 root users 3696027648 2006-11-28 20:53 /Disco40/dvdiso/openSUSE-10.2-RC1-DVD-i386.iso - -rw-r--r-- 1 cer users 3696033792 2006-11-30 12:41 image.iso
Some kind of sector completion?
At least, I know that I can now try to install the rc1. Too late, perhaps.
