unable to write data file to dvd

[somae]

I've been trying to write data files to dvd+rw discs without success. The files were created by "gsplit" and originally was a 9gb backup file. It seems to be able to load the file, but the "build" icon is dimmed.

 

I've attached the log file.

 

Help appreciated.

You don't have a drive that can burn DVDs.
