Burned DVD crypted

ksmoroni · #1 16th September 2006, 03:40 PM

Hi!
I'm trying to use Linux tools instead of Windows software to make backups of my DVDs before they get too scratched to play anymore. Here's what I did.

I used dd to build an iso of the original DVD. The command was basically:
dd if=/dev/dvd of=dvd.iso bs=1024

To make sure that the iso was ok, I mounted it and played it with Xine; it worked great!

Then I put a blank DVD+R Double Layer disc into my DL writing drive that has written many DL disks successfully using Windows tools. Then I used Nautilus to burn the iso to the disc. However, the disc this produced was not playable. So then I tried
growisofs -dvd-compat -Z /dev/dvd=dvd.iso

No errors are reported during the write process, and both methods exited normally indicating that everything was okay. However, when I put the disc in the drive and try to play it with Xine a little intro starts up and right before it gets to the menu the following error appears

The source seems encrypted, and can't be read. Your DVD is probably crypted. According to your country laws, you can or can't install/use libdvdcss to be able to read this disc, which you bought. (Media stream scrambled/encrypted)

The disc will not play in a regular DVD player or under Windows.

I appreciate your help!

Don't dd the dvd onto the hard drive - use instead dvdbackup with the "-m" switch: this will create an unencrypted dvd directory structure on your hard drive. The use K3b to burn a video-dvd. Use dvd+rw until you're sure that the procedure works...

got aq example of how to use dvdbackup?

i used k9copy once and it failed to create the main ifo file leaving me with 7.2 gb of wasted movie. anyway of generating the ifo file so i can compress and burn ?

In addition to the native Linux tools mentioned previously, you could also use DVD Shrink under Wine... it will take some googling to find a place to download DVD Shrink 3.2.
Once you get the installer, make sure you have wine (do a "yum install wine" if you don't have it), then run the DVD Shrink installer through Wine.
This app works remarkably well, despite that it isn't a native Linux app. It's unfortunately that it's a closed source Windows app, but if you're okay with that, then it's an easy solution.

Just put the disk in your dvd drive (/dev/dvd is needed...), cd to a directory of your choice with enough space to hold the entire dvd and issue in a terminal

Code:

dvdbackup -m

The entire dvd will be "mirrored" ("-m") on your hard drive and unencripted. The IFO file will be part of the directory structure. With a DL compatible burner, you just have to burn the directory structure to a DVD-Video (K3b does this for you: otherwise you first create an iso and then burn it with your favourite app).
As for compressing to DVD5, I can't really give hints. I suppose that a program able to access dvd directory structures on a hd as they were real dvds can do the job - certainly mencoder can.
I remember a powerful script called lxdvdrip which works like a charm... livna has it - but no menus, I think.

Thanks everyone for your help so far!

OK. So I've run into some trouble using dvdbackup.

1) I downloaded dvdbackup and libdvdread from sourceforge. However, I ran into some strange error trying to compile libdvdread. Then I learned that I already had libdvdread installed v0.9.5-2.fc5. However, when I tried to compile dvdbackup, I couldn't find the /libdvdread/include and /libdvdread/bin directories that the INSTALL file says are necessary for gcc to compile dvdbackup.

2) So, I found an RPM for dvdbackup for FC4. It installed fine. However, when I run it, I get the following error:
dvdbackup -M -i/dev/dvd -o/backup/dir
dvdbackup: symbol lookup error: dvdbackup: undefined symbol: UDFFindFile

Anyone know what to do with this?

Thanks!

http://dvd-create.sourceforge.net/download.shtml

is this the dvdbackup you are referring too

becuase its not compiling and i have the needed libdvdread
however it came from livna or fresh, not from the site listed on that download page

ksmoroni · #9 16th September 2006, 07:09 PM

steve941, that is exactly where I started. You are also having difficulties compiling?

Have you tried the beta version?? seems to work a little better for me and actually works, just tested it out yesterday. Previously i was using your command line dvdshrink rpm, but i found this to just work a heck of a lot easier.

The instruction for succesfully compiling dvdbackup are here, thanks to giulix

They works perfectly with libdvdread 0.9.6

LocutosOfBorg: Those instructions worked perfectly! Thanks! I'm running dvdbackup right now to see what happens.

Well, using dvdbackup and K3b seems to have almost worked. I can play the DVD in WinXP on RealPlayer, but not in a normal DVD player and when I try to get Xine to play it, I get two error messages that pop up right away:

1) The source can't be read. Maybe you don't have enough rights for this, or source doesn't contain data (e.g: not disc in drive). (/dev/hdc)

2) -xine engine error-
There is no input plugin available to handle 'dvd:/'. Maybe MRL syntax is wrong or file/stream source doesn't exist.

Other DVDs will play in Xine just fine, but my newly created DVD will not. Did I use K3b wrong? I started a new video DVD and put all of the files that were in the VIDEO_TS directory that was created by dvdbackup into the VIDEO_TS directory that was started by K3b and then burned the disc. Did I miss something?

You are allowed to make back ups of you DVD/CD/games and it's all legal as per The US Supreme Court!
If you go to

HTML Code:

http://www.doom9.org/

you will find multiple flavors of software to help. They are windows based. The best which I use are DVD Decrypter and DVD Shrink.
DVD Decryptor used to work under wine in the earlier 9.x versions after 9.9 it went became useless. There is probably some way to get it to work but I (the farthest thing from a coder that can be) have not been able to get it to work and the support group for wine is too busy to worry about those kind of things so not much help there, user forums seems to be more games based so little help there either.
Seem to me that after the developers fought the right for the existence and the legality of their program, which they won,

they went bankrupt and were unable to continue so it was published to the net. I think it's open source, would really be great if some one could port it to Linux!!!!!!!!
