Re: how to copy and/or rip DVDs with Debian?

Hi everybody,

First happy new year to all!

Second - please bear with me, I am a DVD-issue newbie & ignoramous,
but I need some help.

I am DESPERATELY trying to copy encrypted commercial DVDs but nothing
works. Programs such as k9copy or k3b get cold feet with encrypted
DVD so I decided to use the very good and simple CLI tools dvdbackup
and growisofs. This is what I did:

First I make an image of the source DVD with:

dvdbackup -i /media/hdc/ -M -o /home/vees/DVDBackups/ -n
NameOfTheBackupedDVD

And that works great.

Then I tried burning the image to a DVD+RW with:

growisofs -Z /dev/scd1 -dvd-video
/home/vees/DVDBackups/NameOfTheBackupedDVD/

This worked great too, as long as I copied small DVDs, less than the
4.7GB of a typical DVD+RW. When I tried with a bigger DVD, the first
part worked, but the burning did not. Here is the error message I
got:

:-( /dev/scd1: 2295104 blocks are free, 3589847 to be written!

I tried overburning with the -overburn flag, but each time I got the
same input/output error several times. Here are two examples:

I turns out that I needed either a Dual Layer DVD+R (DL) or a Double
Layer DVD-R(DL) which each have 8.5GB of space (This is the first
time I had heard of such double-layer DVDs)

Today I bought three DVD+R(DL) and all went perfectly until I stuck
the DVD into my regular (living room) DVD player which could not read
it! I tried on my computer with mplayer and it could read it with no
problem whatsoever so the DVD itself is not at fault. I can only
conclude that some DVD players do not play DVD+R(DL).

Except. Except that I was given several copied DVD by friends which
my DVD player *did* play. Which brings me to the only logical
conclusion: there must be a way to "squeeze", for example, a 6.9GB
movie into a "regular" 4.7GB DVD+RW. (This is what the software of
my windoze-using friends seemed to have done.)

HOW DO I DO THIS WITH DEBIAN?!?!?!?!?!?!??!

Also - the computer I work on is an ancient 300MHz machine without
soundcard (too old) so there is no way for me to "check" a DVD on it.
I can run it on anther computer (using a live-CD of BSD with mplayer)
or I can try the living room DVD player attached to my TV. This is
the reality of not being rich and I cannot afford anything better. In
any case, I do believe that dvdbackup and growisofs do not care about
encryption in the least and they simply copy byte-by-byte regardless
of what it is they are copying (yet another reason to use them instead
of a GUI copying program).

My burner is not the problem. It can handle both DVD+R(DL) and
DVD+R(DL). Just in case, here is some info about my Maddog MegaSTOR
18X Triple-Format DVD-RW DVD burner (which supports Double Layer
DVD+R/DL and Dual Layer DVD-R/DL at 8x)

==>>Also - how can I 'rip' a DVD into an mpeg or avi file?<<==

Kind regards & may thanks in advance!

vineyard,
Your win-friends should have used dvdshrink for that. I found K9copy to
be the closest alternative in the linux world. when I first found it I
got very happy, but by now, k9copy crashed enough to lower my happines a
gret deal. It seems, indeed, to be unable to deal some drm-infected media.
If you like the cli, I'd strongly suggest that you read and try this:

http://www.linuxquestions.org/questions/showthread.php?t=244913&highlight=dvrequant

which is as simple as a bunch of commands can be. And they give you a
lot of freedom, once you understand whats going on. The author also
wrote a script to automatize the whole thing.

DVD's are mpegs, as said. You can concatenate them and them demux,
requantize, remux, and have them shrinked. I guess that's what all apps
do, in one way or another.
And regarding your dvd player, try to check what hardware and software
specs are supported, in the manual.

I have just returned from my mother-in-law's, and her dvd player
couldn't read a mpeg movie written to a regular 4.4GB dvd-r. This is
curious: in the other hand, my mother bought a dvd player (without a
clue on brands and models...) which we found to be quite smart, reading
several standards of media, and also mpeg files written as 'data disc'
(like there can be another kind...). But as a rule, these devices are
stupid. Computers are evidently more programmable. So, to succeed
reading a disc in a dvd player, you have to go through a bit of
trial-and-error, with media types and procedures.

Most new dvd players read rw media, but older ones don't. And, a 'double
layer' media is quite different from a 'double face' or 'double sided'
media (the name may change). A 'double layer' media is seen by the
system as one single storage device with 8.5GB. That's why you can copy
a commercial dvd into it without any black magic. If your final media is
4.7GB (4.4GB actually), you are stuck into having to shrink it.

And: doing all this in a 300MHz system will be painful, sorry to say that.
