Could you explain whyt you understand by this text?
Without understanding your problem, I don't know how to help.

See above, this seems to be a very vague description and even if I did know
what "in same ECC block" could mean, this still does not clearly explain
whether this is expected or should be avoided.
Also note: UDF does not have ECC blocks...

The second is definitely not related to the UDF specification as this is at
file level and thus content related but not UDF structure related.

If you do not set a volume descriptor, how should mkisofs know?
Did you read the man page?

Iso "level 4" is a method in mkisofs to tell that the ISO-9660 filesystem part
should be ISO-9660:1999, see man page.
