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.
