My boss bought a DVD from United States and need to show the movie to his colleague..
Afraid of his colleague loosing his DVD, he needs to create another VCD from the DVD to lend it to them.
Since it’s only a 25 minutes DVD presentation, I believe I can create a SuperVCD (SVCD) instead of VCD because SuperVCD has better quality.

VCD
Resolution NTSC/PAL: 352×240 & 352×288
Video Compression: MPEG1
Audio Compression: MPEG1
Size/min: 10 MB/min
Min/74 minCD: 74min
DVD Player Compatibility: Great
Computer CPU Demanding: Low
Quality: Good

SVCD
Resolution NTSC/PAL: 480×480 480×576
Video Compression: MPEG2
Audio Compression: MPEG1
Size/min: 10 – 20 MB/min
Min/74 minCD: 35-60min
DVD Player Compatibility: Good
Computer CPU Demanding: High
Quality: Great

I found “The Ultimate Solution” by Manfred Bittersam on how to convert DVD to Video CD.

This guide describes how to convert a PAL-16:9-DVD into several 4:3-VideoCDs with great picture and sound quality

Remark:
The conversion times were evaluated with a 150 min film on an 866 MHz machine.

*** what you need:

- DVD Decrypter
- DVD2AVI + VFAPI Plugin
- TMPGEnc
- Nero

*** This guide is divided into 7 steps:

1) Decrypting
2) Creating FILM.D2V and FILM.WAV
3) Creating FILM.M1V (=Video)
4) Creating FILM.MP2 (=Audio)
5) Multiplexing
6) Cutting
7) Burning

===============================
*** GUIDE:
===============================

1) Decrypting:
a) Copy the whole video_ts directory from the DVD to a directory on your harddisk (e.g. “C:\TheDVD”).
b) Use DVD Decrypter to decrypt all files in the directory “C:\TheDVD” (you can leave all settings unchanged)

2) Creating FILM.D2V and FILM.WAV:
a) Start DVD2AVI
b) Select the VOB files you want to convert:
File…open…*.VOB
Add…*.VOB
OK
c) Move the scroll bar to see whether the VOB files are in the right order and displayed correctly.
d) Optional: Select a part of the film using the buttons “[" and "]”
e) Audio…Dolby Digital
f) Audio…Decoding…Track1 (original language) or Track2 (translation)
g) Audio…48->44.1kHz…Normal
h) Audio…Normalize…DRC (=dynamic range compression)
i) File…Save Project…e.g. “C:\MyCopy\FILM.D2V”
-> DVD2AVI generates a D2V and a WAV file (conversion time: 5 hours)
Warning: The D2V file is just a pointer to the VOB files.
So don’t delete the VOB files after this conversion!

3) Creating FILM.M1V (=Video):
a) Start TMPGEnc
b) Video Source…Browse…”C:\MyCopy\FILM.D2V”
c) Click “Configure”
d) Enter configuration settings:
Video:
Stream Type: MPEG-1
Size: 352 x 288
Aspect Ratio: 4:3, 625Line (PAL)
Frame Rate: 25 fps
Rate Control Mode: constant bitrate (CBR)
Bitrate: 1150 kbps
VBV Buffer Size: 0 (automatic)
Motion Search Accuracy: Highest quality (very slow) -but effective
Advanced:
Video Source Type: Interlaced
Field Order: Even Field first (field order A)
Source Aspect Ratio: 4:3, 625Line (PAL)
Image Positioning Method: Center (preserve aspect ratio) or Center (custom size) with 483 x 386, if you want to kill the black bars.

*** If you want the perfect quality
(conversion time: five days!)
use the filters as follows:

DoubleClick on “Noise Reduction”-checkbox:
Select Spatial: 100
Range: 4
Temporal: 100
Enable Filter = TRUE
High Quality Mo = TRUE
Click “OK”
DoubleClick on “Edge Enhancement”-checkbox:
Select Horizontal: 127
Vertical: 127
Enable Filter = TRUE
Fieldwise = TRUE
Click “OK”
DoubleClick on “Deinterlace”-checkbox:
Select “Even field (adaptive)”, Enable filter = TRUE.
Click “OK”

*** If you want acceptable quality
(conversion time: 24 hours)
set the checkboxes above to false (no filters).

The “Do not change frame rate”-checkbox = TRUE.
Click “OK”
e) Click “Encode”
-> TMPGEnc generates a M1V file

4) Creating FILM.MP2 (=Audio):
a) Start TMPGEnc
b) Delete all filenames
c) Audio Source…Browse…”C:\MyCopy\FILM.WAV”
d) Click “Encode”
-> TMPGEnc generates a MP2 file (conversion time: 30 minutes)

5) Multiplexing:
a) Start TMPGEnc
b) File…MPEG tools…Basic Multiplex
c) Type: MPEG-1 VideoCD
Video Input: “C:\MyCopy\FILM.M1V”
Audio Input: “C:\MyCopy\FILM.MP2″
d) Click “Start”
-> TMPGEnc generates a MPG file (conversion time: 15 minutes)

6) Cutting:
a) Look at the size of your MPG file, and decide how many parts you want to make of it.
One part should not be bigger than 620 MB, if you use 74 min discs.
b) Start TMPGEnc
c) File…MPEG tools…Cut/Join
d) Type: MPEG-1 VideoCD
e) Add…”C:\MyCopy\FILM.MPG” -> The list shows a new entry
f) Click “Edit”
g) Select a part of the film using the buttons “[" and "]”
h) Click “OK”
i) Output…Browse…”C:\MyCopy\FILM1.MPG”
j) Click “Start”
-> TMPGEnc generates your FILM1.MPG
(conversion time: about 15 minutes, depending on the location of the part selected)
k) Repeat (f) to (j) for each other part (FILM2.MPG …)

7) Burning:
a) start Nero
b) select the icon “Video-CD”
c) Click “New”
d) From the Explorer on the right, choose “C:\MyCopy\FILM1.MPG”, and drag it into the list on the left.
-> Nero checks whether the MPG file is VideoCD compliant or not.
e) When the test is ready, click File…burn CD
f) Enter a volume descriptor
g) Click “OK”.
-> Nero burns the CD
h) Repeat (a) to (g) for each other part (FILM2.MPG …)
