DVD to RA: Extract Audio from DVD(Digital Versatile Disk) Video to RA(RealAudio) with River Past Audio Converter, DVD2RA converter, conversion
DVD (also known as "Digital Versatile Disc" or "Digital
Video Disc") is
a popular optical disc storage media
format. Its main uses are video and data storage. Most DVDs are of the same
dimensions as compact discs (CDs) but store more than six times as much data.
DVD-Video discs respectively refer to
properly formatted and structured video content. It uses MPEG-2
for video compression, with AC-3,
MPEG audio for multi-channel audio support.
To decode DVD, you will need both GPL
MPEG-2 Decoder, and AC-3
RealAudio was developed
by RealNetworks and supports FM-stereo-quality
sound. To hear a Web page that includes a RealAudio sound file, you need a RealAudio
player or plug-in, a program that is freely available from a number of places.
More information is available on RealNetwork

Launch River Past Audio Converter
Once River Past Audio Converter is installed properly, launch Audio Converter.
Click on the "Add DVD" button on the tool bar. The standard directory open dialog appears. Select your DVD drive or select the "VIDEO_TS" directory.
Select the drive and click "OK". Video Cleaner will parse the directory and add all the video chapters on the disc.
Handling of encrypted DVD's
Most commercial DVD's are copy protected. Our software cannot convert from encrypted DVD's. You can use a third party software to rip the DVD to hard drive first, then browse to the VIDEO_TS directory in our software.
Difference between "Add DVD" and "Add Files"
Do not use "Add Files" to select the VOB files on the DVD disc. A DVD contains many video clips, which are then divided into cells/chapters. All of the video clips are then streamed together in one big block. The VOB files on the disc is just a way to divide the block into 1GB files to be compatible with older operation systems like Windows 95, who has a file size limit.
Each VOB file on the DVD may contain multiple videos. Each video may span over multiple VOB files. If you use "Add Files", only the first clip in that particular VOB file will be parsed and added.
This picture below makes it easier to understand.
In this example, VTS_01_1.VOB contains a still menu, chapter 2, and then the beginning of chapter 3. VTS_01_2.VOB contains the end of chapter 3, and beginning of chapter 4. VTS_01_3.VOB contains the middle of chapter 4. VTS_01_4.VOB contains the end of chapter 4 and beginning of chapter 5, and VTS_01_5.VOB contains the end of chapter 5.
If you use "Add Files" to add VTS_01_1.VOB, you will only get the still menu. If you use "Add Files" to add VTS_01_2.VOB, you will get the end of chapter 3... This is how file based decoding works.
That's why you should use "Add DVD". We will parse the DVD information and find all the cell breaks. You will get to select which cell to convert, from 2 to 5. Still menus are ignored.
If you encounter an error when adding the DVD, please make sure you have GPL MPEG-2 Decoder filter and AC-3 Decoder filter installed.
