[Stgt-devel] How to setup a DVD RW

[ronnie sahlberg]

Can you try using dvdwriter like this :

dvdrecord -dao -ignsize -overburn dev=/dev/sgX ./IMAGE.iso

and just verify that that works.

If that works it is most likely that there is something missing in the
emulation of DVD+R that
K2B needs to be happy.
