Copying DVDs on Dual layer disc

Is there a program I can use that will make a 1:1 backup of a DVD on a dual layer disc so I don't have to use multiple programs to backup a DVD. I'd like to just use 1 program that will rip then burn a DVD onto a dual layer disc.
I'm tired of my friends returning my movies scratched or even worse, not returning them at all.

DVD Decrypter

MODE->ISO READ
MODE->ISO WRITE

Really quite simple.

Awesome, you are the man.

Hi, I´ve tried succesfully this with NERO 7, DVDFAB Platinum (choose option double layer) and DVD-Clonner.
Good luck and also ANYDVD or REGION CSS free

not that i want to discourage posting of solutions, but yours is far more complicated than it needs to be. just use Gurm's method.

Might I also suggest using VERBATIM DL media. I've had very good results on both PIONEER 110 and BENQ1640 burning @ 4X.

Hi people and thanks for posting advice on this problem. I have been backing up my dvd's using dvdshrinker and imgburn for a while but I too wanted to burn dvds 1:1 onto dual layer dvds.

I have tried gurms method and used the dvddecrypter iso read process on a dvd movie I own, which completed successfully.

I then put a Verbatim 8x DVD+R DL disc into the drive and tried to use the iso write process with the iso file I had created.

The first message said 'You should have selected the mds file and not this one. I'll do it for you automatically this time, but don't do it again!'

O.k. so no problem there I just clicked OK and then clicked on the 'write' button hoping things would work.

Soon a second more serious message came up, this read as follows;

'I/O Error!

I cant understand why this isn't working as my drive can write blu-rays discs, or is it a software mistake I am making. Any help would be appreciated as I've spent a fair amount on the DL Discs.

I forgot to say that in between the first and second messages I also get another error, it reads,

'Failed to set L0 Data Zone Capacity!

Reason: Power Calibration Error
