libburn and thus the cdrskin project are currently aquiring own capabilities
|
||||
to burn to DVD media. For now restricted to DVD+RW and DVD-RW and to single
|
||||
tracks.
|
||||
|
||||
To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
|
||||
they would write to a traditional tape device. Try old tape archiver
|
||||
commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
|
||||
I have heard rumors that DVD-RW in mode "restricted overwrite" would be
|
||||
block device ready, too. My burner is not a real friend of DVD-RW and
|
||||
in an experiment the burn worked fine - but the result was not identical
|
||||
to the stream sent to the device. I had similar failure with DVD-RAM, too.
|
||||
|
||||
Beware of the impact of a slow block device on overall system i/o buffering.
|
||||
It is wise to curb its input to a speed which it is able to deliver to media.
|
||||
Else your i/o dedicated RAM might buffer a big amount of stream data.
|
||||
A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on
|
||||
overwriteable media. This is not the same as multi-session writing of cdrskin
|
||||
with CD media, but retrieves additional information from the existing ISO
|
||||
image and finally manipulates the start sectors of this existing image.
|
||||
So for growable ISO filesystems on DVD-RAM or DVD+RW growisofs is the only
|
||||
choice, currently.
