[Stgt-devel] How to setup a DVD RW

[Albert Pauw]

Finally can confirm that the dvdrecord command works.

What I did wrong was NOT using a file with length zero to start with as 
the backend,
so it was seen as a readonly CD/DVD, forgot that READMEs are there to 
read ;-) because
it can be found in README.mmc

K3B and nautilus (the Fedora desktop, rightclick  "Open CD/DVD Creator) 
don't work. They both keep asking to insert a blank CD/DVD.
As said the dvdrecord command works like a charm, so it is mostly working.
