Hi,

You are using wodim, not cdrecord.
The floating point error is only a final
glitch after writing already failed.

The program has few clue about DVD+RW.
You probably caused this by option -dao.

That's the very first write attempt.
Already failing.
Looks like the program did not start
background formatting on unformatted
DVD+RW media before writing began.


It is advisable to use a different program
for DVD purposes. E.g:
  growisofs, cdrecord, cdrskin, xorriso.
(I am author of the latter two.)

DVD+RW should be simply writeable via their
device file. Try:

  dd if=newworld.iso bs=2048 of=/dev/dvd

Maybe the kernel is smarter than the burn program.


Have a nice day :)
