[linux-audio-user] Extracting tracks from DVDs

[ram]

On Debian based Linux distributions, e.g. Debian Sarge, Fervent-STG, and so
forth, I find the following two command line programs very useful for
extracting and manipulating DVD contents:

dvdbackup  (to get the info on the hard drive)

ffmpeg (for audio and/or video transcoding/format conversion)

They are usually supplied with the distribution itself.  You may need to add
deCSS depending on your region.  Otherwise the dependency issues are not too
bad, unlike dvd::rip 

The manual (man) pages are also reasonably complete and clear.

Good luck,

A Nonny Mous
