Well I guess you take me out of context -
I said: ‘Burn as slow as you can’.
May be that is insufficient clarity or detail, I don’t know. But I certainly never meant to imply that the OP force a burn at a speed not associated with the optical media.
But I do stand by my comment and it’s implication from my understanding, that burning the media as slowly as you can (given the limitation of the media and hardware) is the best policy.

I understand.

Then we agree that we disagree

Problem is that most people will try to burn at the highest rated speed. This works ok for most multi media things because a bit wrong here or there won’t hurt too much, but can lead to bad installs of software where a bit here and there matters. Also people tend to buy the cheapest **** disks they can find. Proper burning software should not in general allow one to burn at a lower speed then recommended, even though it may be possible to force the issue. So for naive Windows users caf’s instructions work like a charm. The important thing is that if you burn at the highest possible speed you eisk making coasters.
I think the bigest part of the problem lies there. I only use verbatim that are, IMHO, the best out there.

Should not be a problem if media is good and burner is good 
I simply leave the burner at auto and let it figure the speed. If I suspect
problems I drop speed a notch. The most likely problem would be the
disk-memory-dvd system not being able to handle the large data stream;
although recent hardware have protection for that.

Yes, bad media is really an issue.
Also, it should not be an issue with our isos, because there are package
checksums that should impede a bad rpm from being installed. That is, it
should result at worst in a needed package not being installed, which would
be catched later with a “zypper verify”.
The other possible issue is the installer itself being faulty. Anything
could happen, then. I don’t know if the installer does a self check of the
install image (not the whole dvd, that’s optional). Years ago, I created
some .exe pograms that did a checksum of themselves, so it is possible.
However, we know that bad dvds do result in bad installs, so… either I’m
wrong or I missed something.

Quite possible.

In one of the links I posted, there is a list of media classified by
quality - and verbatim is 1st class in that list.

What I’ve learnt through this problem is DO NOT BURN AT TOP SPEED, you’re not participating in Le Mans.
I burnt the disc at 8x using ImgBurn. The built in feature checked the completely of the burnt disc. Although it was long, but also improved my patient.
Good: Sony CD-R
Not so good: Imation CD-R
