Ripping DVD's and creating (Super) VideoCD's
...
There are several ways to copy a DVD.
The most compatible method for home-use would
be the use of the (Super) VideoCD format. This allows you to copy
a movie to 2 (or more) VideoCD's or Super VideoCD's. We do
need an MPEG (1 of 2) encoder for this. Take a look at the formats
page for details on the resolution of either choices.
So the downside is that one movie can take up
2 or more CD's. On the otherside: the huge advantage is that you
playback these movies on a stand-alone DVD player - so you won't
need a PC for playback!
Note: Read the disclaimer!
Note: DivX
is a very good alternative if you decide to play the movies on PC's
only.

How does it work?
Copying a DVD is based on these steps:
Different (mostly freeware) applications can help you
with this.
There are several ways of doing this:
- DVDx - Nice
and easy, all in one go ...
- FlaskMPEG 6 -
Easy too, and also in 1 go
DeCSS and Copying to Harddisk
Most DVD's are protected against copying and/or editing.
To copy a DVD, we first need to remove the encryption (CSS - Content
Scrambling System) of the so called VOB (Video on Demand) files. This
process is called DeCSS - refering to the first program that could do
this.
Older rippers, like PowerRipper, uses the output of
a software DVD-player to rip audio and video. This technique is difficult
and out-of-date (but smart though!).
There are multiple DVD-rippers out there, but I have
to say that in my personal opinion SmartRipper
is still the best.
This program decodes the VOB (Video On Demand)
files while copying them to your computers' harddisk.
Note: CSS encoding has been changed a
bit since the introduction of DeCSS - insteda of only one key per movie
the DVD now requests multiple keys per movie. Not all DVD-rippers are
capable of doing this - Smartripper however is able to handle this just
fine!
Conversion to MPEG1 or MPEG2
After copying the requiered DVD files, we must transcode
(re-compress) the movie to MPEG. The standard
compression for a DVD movie is MPEG2 and uses quite a lot of space (often
about 5 Gbyte per movie). The difference with MPEG2 for Super VideoCD
is that SVCD uses only half the width per image and SVCD uses a lower
bitrate.
Conversion to MPEG1 or MPEG2 is pretty easy. Very common
tools for this are DvDx and FlasKMPEG
6. The result can be played with a standalone DVD/VCD-player, Microsoft
Media Player (v7 or newer) or for example with PowerDVD.
Note: Windows Media Player cannot playback
MPEG2 movies. You will need a DVD-playback-program which installs a codec.
MPEG1 will work just fine.
Putting it on a CDRom
A MPEG file (we use the extension .MPG for these
files) can be put on CD using applications like Nero that offer templates
for both VideoCD and Super VideoCD.
