===Linux DVD Writing===
I'll only focus on growisofs although one will find graphical tools like K3B much more flexible.

==Write a pre-mastered iso image==
%%
# Make sure you got the device name right
cdrecord --devices
# Following option disables the disc from further writing, which makes sense for iso burning
growisofs -dvd-compat -Z /dev/scd0=filename.iso
%%

Sadly, my first writing failed with the following errors. It's a double layer disc. There goes HK$30 :(
%%
:-[ WRITE@LBA=cd630h failed with SK=3h/ASC=02h/ACQ=00h]: Input/output error
:-( write failed: Input/output error
/dev/scd0: flushing cache
/dev/scd0: updating RMA
/dev/scd0: closing disc
%%


==Writing files to dvd==
There are actually directly from the man page.

%%
# Write data for the first time
growisofs -Z /dev/dvd -R -J /some/file

# Adding more files to the disc
growisofs -M /dev/dvd -R -J /more/files

# Make sure to use the same options for both initial burning and when appending data.
# To finalize the multisession DVD maintaining maximum compatibility:
growisofs -M /dev/dvd=/dev/zero
%%

==Create iso from dvd data disc==
The conv options are important. Without them, dd seems to create incomplete image. Brasero handles that automatically. It'll be interested to see what command brasero calls.
%%
dd if=/dev/sr0 of=/out.iso bs=2048 conv=sync,notrunc
%%

==Side notes from LinuxJourmal==
There is an article from LinuxJournal that describes additional steps required with creating an iso image, see http://goo.gl/ilgq4
%%
isoinfo -d -i /dev/cdrom
dd if=/dev/cdrom bs=blocksize count=count
of=/path/to/isoimage.iso
%%
