My DVD is unbelievably huge

drcouzelis · 2011-05-31 18:13:15

I bought an expensive set of video DVDs for class and am trying to make a personal set of backup copies. I'm failing miserably. I've had many strange experiences trying to copy these discs, but here's the point:

The DVD appears to contain 48 GB of data.

First, I made a copy with K3B, but it didn't play in my DVD player. Then, I made a copy using k9copy. I could play the copied image correctly using VLC but the ISO was 16 GB. Now, I'm currently trying to make a copy using dvdbackup. It hasn't finished yet, but the image directory is currently around 26 GB. I used the "du" command on the DVD directory mounted under "/media", and apparently this DVD is 48 GB big.

Is this normal? I'm so confused. Isn't the contents of the DVD supposed to be, you know, around 4.7 GB?

Edit: The "df" command reports that the mounted DVD is around 4.5 GB. Now I'm more confused.

Thank you.

Try with dd:

dd if=/dev/dvd of=/wherever/you/want/to/put/your/copy.iso

Then you can burn it with k3b or cdrkit command line tools.

It's normal, yes. Welcome to the world of DRM. Over the years they've tried all sorts of crazy stuff to "protect" the content on the discs. What you're seeing is one of them. DVDFab HD Decrypter can handle all this crap and works nicely in wine. So I suggest you use that. Possibly a 'mplayer dvdnav://1 -dumpstream -dumpfile blah.vob' could work too.

Thank you for the suggestion. Unfortunately, it produced a 17 MB ISO file that wouldn't play in VLC.

Helping with an illegal activity is not allowed here. I'm not doing anything illegal.

I was afraid of that.

I'll go ahead and try the DVDFab application. Thanks for the advice.

Also, the mplayer command does appear to work, but I'm going to see if I can't get a complete copy, menus included.

Have you tried ddrescue? It manages my encrypted dvds

pacman -S ddrescue

ddrescue /dev/dvd file.iso

IANAL
Actually, I think you are in danger of violating the DMCA. If you are indeed in New York, I think you will find that the anti-circumvention clauses do not apply to what you are trying to do.

Technically, we (US residents) are not even supposed to be using de-css

Kind of Orwellian, isn't it?

I am leaving this thread open for now, but please, everyone mind the rules.
