can "dd" be used to copy a DVD & growisofs syntax neededI was told that "dd" can be used to exactly copy a DVD byte by byte. Is that true? How could I do this? ALternatively, does anyone know the correct flags and syntax to copy a DVD with growisofs? I would be copying from a commercial DVD unto a DVD+RW? Note: I often encounter errors when reading a source DVD which blocks my k3b. This is why I would like to force an exact copy of the DVD, errors either skipped or, better, included.

it works for CDs...
Just:
dd if=/dev/cdrom of=/home/pirates/mypiratedcopy.iso
should work - and you can then do:
mount -t iso9660 /home/pirates/mypiratedcopy.iso /mnt
So in principle something similar should happen with SOME DVDs (certainly true of data discs). I don't know if it will be true for a movie-only type DVD - if such DVDs only have extra 'info' tracks for the sake of being able to play on a computer but most data is in fact in a format alien to Linux, then a 'dd' copy will fail. The firmware in the drives are rather intelligent these days, but not intelligent enough to figure out that you're trying to do a bit copy and obligingly do a bit copy - it may become totally confused if you try to access a disc that way.
Depends on what type of DVD it is
Hi vees
Using dd like pinniped suggested works for data DVDs.
If you want make a copy of video DVDs or audio DVDs, this only works for unencrypted data.
From what you call "commercial" I assume that it's somewhat encrypted, so using dd will not work. I looked through the Debian package cache and found 'dvdbackup'. This tool may be useful.
Burn a iso image with growisofs like this:
growisofs -Z /dev/cdrom=/path/to/image.iso
Cheers, Georg
still can't copy the *%&$$*#!!!*#@!!! DVD :-((
ok. I tried dvdbackup, I tried k9copy and I tried k3b. Nothing works. Surely I am not the only GNU/Linux user who wants to backup/copy his commercial/encrypted DVDs?! Guys, who do you do it?!
dvdbackup gave me a nonsensical error, worked for a while without actually writing anything, then stopped. k3b tells me that the DVD is encrypted while k9copy tells me that the DVD is not "open" (both when I mount it and when it is not mounted). Grrrrrrrrrrrrr [teeth grinding, rolleyes]
I got my DVD burner to work now, both with k3b and with growisofs and all I need is bypassing this irritating copy-protection. Surely there must be a simple CLI application out there which simply takes a commercial/encrypted DVD and makes a byte by byte copy, copy protections/"errors" included?!
Help!

Hi there.
For k9copy make sure you have all these.
dvdbackup,dvdrtools,dvd+rw-tools,libdvdcss2,libdvdplay0,libdvdread3,transcode.
This might be of use.

Greetings my friend!
I will follow your advice, but I also hope that maybe somebody soon will make a distro which ships with all that ;-)
Kind regards, iassu,

alas, k9copy gives me a "DVD not open" error
Howdi,
I am back with the same problem. I apt-get installed all the libraries you mention, but still k9copy give me an immediate error message "DVD not open". I tried using all THREE of my DVD drives as input source, both mounted and unmounted, I even pointed to the mountpoint to try to get k9copy to "see" the DVD as "open" but still I get the same error message. I do not think that this is an encryption issue, but a more basic "app does not see disk" kind of problem.
Any ideas or suggestions?
Thanks,
VS

What version of k9copy are you using and on what box?
When you open k9copy does the "Input device" point to the right place? You may have to do it manually.
Can you play dvd's ok?
