[Stgt-devel] How to setup a DVD RW

[Albert Pauw]

Hi Ronnie,

I must be doing something wrong here, here is the output of dvdrecord:

[root at orange ~]# dvdrecord -dao -ignsize -overburn dev=/dev/sr1 ./fdfullcd.iso

As you can see, it doesn't see the disk.

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.
