Checking media
Found DVD+RW media
No need to format DVD+RW media more than once
It may simply be overwritten

Overall progress - 100%
taking about 1 minute to finish.


Burned DVD ISO image again.
Same result - no burning with the same warning displayed as above.


Formatted DVD+RW, this time with "Quick format" unchecked
Same result as "Quick format" checked. The light of the DVD writer did not glow. I don't think there was any action taken.

Would K3b and relevant tools on Knoppix are not up-to-date to run DVD Writer?

Please help. TIA
