Note,
if you plan to convert DVD files to MPEG/AVI, view the VOB
Conversion Guide instead. The steps outlined below are only
for those wanting an identical "rip".
There
are several things you need to know before you can successfully
rip a DVD :
CSS
encryption : This is the encryption method used in DVDs. This
encryption does allow files to be copied off the DVD, but
the resulting files will contain garbage data that will be
useless.
Rippers
: A ripper is a program that allows you to break this encryption
and "rip" out the files from the DVD, without it being turned
into garbage data.
VOB
Files : VOB files are the default format of DVD movies. This
files may contain several streams of audio/video "multiplexed"
together (eg. chapters/language selections). These files,
once ripped, can be played back with any soft-DVD player that
supports the file opening feature (presently, only the Ravisent/Elsa
player does not).

Before
we start : Because of the way The Matrix is encoded on DVD,
it can be notoriously hard to backup to your hard-drive. Asyd
Rayne was very nice enough to have gone to a lot of effort
to make a guide specially for The Matrix. Please read it :
The
Matrix Backup Guide
What
do you need :
Plenty
of HDD space - 4-6 GB depending on movie
How
to rip a DVD .vob file :
Step
1 : You'll need to download one of these 2 rippers, I recommend
DeCSS v1.21b.

To
install these rippers, simply unzip them into a directory
of your choice. For a selection of other encoding/conversion
tools, please refer to this site.
Step
2 : Insert the DVD disc that you want to rip in your DVD-ROM
drive.
NOTE
: If you get a "ASPI" or "Key not found, disc not encrytped"
or similar error messages, you may need to disable DMA mode
transfer for your DVD-ROM drive. To see how, click here.
Step
3 : Start either DeCSS or DOD Speed Ripper programs and select
the drive that correspond to your DVD-ROM drive. You should
see a list of files, named like VTS_01_0.vob, these are the
movie files. The largest files, which is 0.99GB in size, contain
the actual movie, while smaller files may contain extras,
trailers or navigational menu data.
If
you are using VOBDec, then you need to start a software-DVD
player first, before you can use it to decrypt the VOB files.
Step
4 : For DeCSS/DODSR - Now simply select the file you want
to rip out, select the location you want to rip to, and then
click "transfer" or "rip", and you're away. It can't be more
simple.
For
VOBDec - It's a DOS command line program, so you might want
to get it's GUI for easier usage
How
to extract a .vob stream from a VOB file :
As
you know, some vob files might contain more than 1 movie movies
stream. For this example, I've ripped the file vts_03_1.vob
from the Saving Private Ryan Dolby Digital DVD. There is no
way to find out what exactly is in each .vob file without
ripping them out first, so use some common sense. A trailer
or something will usually be in one of the smaller files,
around 100 MB in size, while the movie might be divided into
3 or 4 .vob files, of around 0.99GB. You can also tell which
files are in series by the file name, where vts_01_0.vob ,
vts_01_1.vob ... are in series (so if one of them is 0.99GB
in size, the whole movie is contained within this series of
files).
Step
1 : Rip the file you want to extract from, for example : vts_03_1.vob
from Saving Private Ryan.
Step
2 : You'll need to download this file

To
install this file, simply unzip them into a directory of your
choice and run the supplied .exe file.
Step
3 : Start the VobTools program and select the file you just
ripped, eg. vts_03_01.vob , and press "Analyze VOB" button.
After a while, the window on the right should display a list
of vob streams contained within, and also will display their
size. Now it's simply a matter of selecting the files you
want (hold shift + mouse button to select more than 1 segment)
to extract out, eg. For my vts_03_1.vob, I ripped out the
two larger files (see diagram below), segments #1 and #3,
and press the "Extract VOB(s)" button.

Step
4 : Just out of interest, the two files I ripped out from
Saving Private Ryan were actually the 2 trailers on the disc
- this is great if you only want to rip a trailer from a disc,
without having to keep the entire 0.99GB file (some trailers
are hidden in the VOB file the actual movie is in).
Step
5 : Remember, in order to playback the ripped .vob file, you
must have a software DVD player that is capable of "file"
opening. So far, only the Ravisent Cinemaster 99 player does
not support this function. You can download these software
DVD player on DVD Digest's download site.
Step
6 : Playback a ripped whole DVD from your hard-drive
You
might be intersted to first make the ripped .VOB files region
and macrovision free
There
are 3 methods that you can try :
Option
1. Below was a suggestion submitted
by Stephan on how to playback ripped DVDs using his Hollywood+
card (also work for soft-Cinemaster and WinDVD) :
...
I only have two partitions and on the bigger one I can put
several movies in different directories. When I want to play
a movie I just move a movies catalogue video_ts (and if exists
audio_ts) to the root directory, start DVDstation, select
D: as the movie drive. The movie starts. When I want to change
movie, just put back the video_ts to its original location
and move the next movie video_ts catalogue to the root. It
is so simple and convenient ...
Option
2. There is a new way to play DVDs from
your hard-disk, without using the SUBST command below. It
is a new software called StartDVD v1.0, and you can download
it here
Option
3. If you want to copy the entire DVD
to your hard-disk, and sort of "emulate" a DVD drive there,
you do not need to create another separate partition. What
you can do is to copy down the directory structure of the
DVD disc you want to copy (eg. if I was ripping The Matrix,
I would make a directory called c:\temp\matrix\ and also make
sub-directories : video_ts and/or audio_ts) and then rip all
of the .vob files to these directory and retain the original
naming. Then copy over all of the .ifo and .bup files (they
are unencrypted) over as well. Now comes the tricky part :
1.
Find the first free drive letter, eg. on my system it is g:\
2.
locate the directory you ripped to, eg. c:\temp\matrix\
3.
go to your start menu => run , or MS-DOS prompt, and type
in (for example) :
subst
g: c:\temp\matrix
note
: the directory c:\temp\matrix\ must be typed without the
last '\' character
4.
Now check your drive g:\ it should "contain" all of the data/folders
found in c:\temp\matrix\
5.
You've just made your first "virtual" DVD-disc. This virtual
drive does not consume any additional hard disk space.
6.
To remove this virtual drive after you've finished with it,
run the following in Start Menu=> run or MS-DOS Prompt (for
example) :
subst
g: /d
Note
: this technique hasn't been tested before (I don't have the
resources to copy over a whole DVD disc), so if it doesn't
work then I don't really know of another way.
Maybe
you have some other technique that I don't know about, and
would like to tell me about it. Either way, send me an email
as to tell me whether it worked for your or not and if you
have any other methods. Thanks.
Now
to play this "virtual" disc, you'll need a software DVD player.
Most software DVD players either let you select which drive
your "DVD-disc" is in (eg. WinDVD and PowerDVD) or automatically
detects the first drive with DVD data.
