Feature:
must have commandline support
must have multisession support

I use mkisofs to create an ISO image, and then growisofs to burn it onto DVD. growisofs supports multisession, I believe.

I will try it.

your three options are growisofs, and this is built into k3b. dvdrecord, which is a hacked version of cdrecord with dvd support which made schily, the author of cdrecord very angry, and the best one is cdrecord prodvd from schily's cdrecord site. searching for cdrecord home on google will find it for you.
you must have a recent version of mkisofs so that you have support for iso images bigger than 2 gig's.

Good point... do you happen to know which version mkisofs started supporting ISO images larger than 2GB? Mine's 2.0 and it does.

this is in the changelog for cdrtools 2.01:

Try to support files >= 2 GB.
Note that mkisofs is not yet written cleanly so there may be problems
if files >= are used. In such a case, please report.


I tried digging through changlogs at ftp://ftp.berlios.de/pub/cdrecord/
They all start with AN-<version number>.
I think the above is for files in the iso image itself. And i guess an iso image would need to be bigger than 2 gigs to have a file bigger than 2 gigs in it. But, i saw a reference to a mkisofs feature that would split the iso image for you.
I've also used split up images from an old windows dvdshrink that had split the iso up into 1 gig chunks. i was able to feed the files to cdrecord-ProDVD with something like: cdrecord-wrapper.sh dev=0,0,0 speed=4 -v image.*

Hi,
Can you elaborate on how you created the split output and test mounted it.

I tried it with
mkisofs -r -split-output -o image.iso user/

It did create 3 iso files but the Trans.TBL file size was zero according to i, which meant that there was problem with the iso creation.

also how does one test mount the series of iso images to check whether the iso creation was fine??

Can you explain me in a bit detail how you did it?.

Thanks a lot,
haoscar

I didn't create them on purpose, and i didn't use mkisofs. the program dvdshrink did it. at first i was using cat and dd to put the pieces back together, like cat image*.* |dd of=all.iso. then i tried once without putting them together and it worked. i never did test an image to see if it worked first.

edit: I just made a normal iso image, and it said translation table size 0. So i take it to be normal.

Hi, All:

Thanks a lot.

I got a cygwin version of cdrecord-prodvd. It works fine for CD, but for DVD-RW, I have no result:

the last 2 lines printed are:

Starting to write CD/DVD at speed 1 in real TAO mode for single session.
Last chance to quit, starting real write 8 secondsAlarm clock

How do you do it, Highhands?

from schily's site.


If you get an "Alarm clock" abort from cdrecord-ProDVD, then you
are experiencing license problems. Possible reasons are:

- Your time and date is set to a value before the link
time of cdrecord.

- You are using a Alpha binary that is more than a year old.
Note that cdrecord-ProDVD binaries that contain the letter 'a'
in the version string will stop working one year after
the day of the creation of the binary.

********
WARNING: If you fetch an alpha binary (the name is something
like 1.11a11 and the "a" inside the version string denotes
the alpha state) please keep in mind that the binary is limited
to work about one year. So please fetch a new binary from time
to time if you are running an alpha version.
********

The time limitation os the binary is independant of the time
limit of a key.

- You are using an expired key.
Check for a new one to verify if the key has expired.

- Your binary has been otherwise broken.
Fetch a new binary and make sure that you select binary
mode (via "set bin") for FTP.

Thanks, Guru.

I get a newer one - Cdrecord-ProDVD-Clone 2.01.01a01 (i686-pc-cygwin)

it says that
cdrecord-prodvd: Drive does not support RAW/TAO recording.
cdrecord-prodvd: Illegal write mode for this drive.

Do I need a key? How could I find out the supported recording mode?

OK! It works now.

Could you recommend a verification tool? I could not make the sformat thing, too many errors under my cygwin-gcc.

Thanks.
