A DVD is comprised of one or more video title sets (VTSes), which contain video information in the form of MPEG-2 video streams. Each disc can have up to 99 VTSes, and each title set can be subdivided further into as many as 99 chapters, allowing DVD players to jump to a certain point within the video stream. Within each VTS, a DVD can have up to eight different audio tracks and 32 subtitle tracks that the viewer can switch between at will. A menu system can be included within a title set, allowing the viewer to select between the different subtitle and audio tracks. An optional top-level menu, known as the video manager menu (VMGM), is used to navigate between the different title sets. One VTS may contain a feature film and another may contain a documentary on the film, and the VMGM allows viewers to select which one they want to watch.
The DVD format doesn't eliminate the differences between the two competing broadcasting formats, NTSC (primarily used in America) and PAL (the standard in Europe and Japan). I live in Britain, so the frame information and resolution details used in this article are for a PAL system, but I point out the differences you need to be aware of when they appear and offer appropriate settings for an NTSC disc.
The DVD specification includes advanced features, such as the concept of region coding, the possibility of viewing different angles of a video stream and simple computations using built-in registers provided by a DVD player. I don't know much about these features, and they aren't discussed in this article. The dvdauthor mailing list is a good source for further information.

I know four possibilities to get videos from a digital video DV camera to the computer's hard disk: dvgrab, kino, Main Actor and cinelerra. I prefer dvgrab, because it is a simple and easy command line tool with no overhead. I bought a big 250GB hard disk and stored all my videos there:
dvgrab --format dv2 --opendml --autosplit --timestamp prefix
There are at least four possibilities to cut and edit videos: avidemux2, kino, Main Actor and cinelerra. I prefer avidemu2 for TV recordings, because it is simple, but has no fancy features. For cuts and simple effects, kino is perfect. More elaborated effects can be created with Main Actor and cinelerra, but Main Actor is more intuitive in handling and seems to crash less often. The biggest problem with Main Actor is that the edit file format is binary and proprietary, and it cannot handle files larger than 2GB. For this, save several smaller videos and collate them using kino. Main Actor, kino and avidemux2 (Save as DVD PS) can export videos directly in DVD format. I don't know whether cinelerra can do this.
PovRay is a program that reads 3D scene descriptions to generate images. This is very useful to create DVD title images or intro sequences. A short example:
#include "colors.inc"
#include "golds.inc"
#include "stones.inc"
background {Black}
camera {location -5*z look_at 0 right 720/576*x}
light_source {<-10,10,-10> White}
union {
text {ttf "timrom.ttf" "PovRay" 1, 0 texture {T_Gold_3B}
translate <-1.5,0,-1.5>
}
box {-1, 1 texture {T_Stone8}}
rotate clock*360
}

The movies can be prepared with avidemux2, cut out the commercials and find the start and end of the movie. With the buttons A and B you can mark the start and end of a region that you can delete with key Del. For saving, you must choose Save as DVD PS. If there is any problem, you may have to remultiplex the movie with dvb-mplex -t DVD -o dvd-movie.mpg movie.mpg. That lasts a long time, but does not reduce quality. You have to do it anyway if you want to burn a video without the use of avidemux2.
Bevor you can burn a movie, you must master a DVD image, given a prepared movie named dvd-movie.mpg:
dvdauthor -o img dvd-movie.mpgdvdauthor -o img -Tgrowisofs -dvd-compat -Z /dev/dvdrecorder -dvd-video imgrm -r imgAll you need to copy video DVDs is the program lxdvdrip.
Other tools are required by lxdvdrip as described in the documentation. Not all of them are described here, e.g. streamdvd from http://www.badabum.de/streamdvd.html.
If lxdvdrip does not automatically choose the right main movie track for copy, you can use lsdvd to list the tracks and choose the longest track by calling lxdvdrip with option -t and the track number.
Unfortunately, commercial DVD videos are limited by a copy protection named CSS. This is the reason, why in the standard installation of a Linux distribution, it is not possible to watch DVD movies. To be able to watch DVDs regardless of copy protection, you need a hacker tool named DeCSS. This may be illegal in some countries, therefore distributors do not deliver the necessary libraries. The easiest way of installation on a SuSE Linux is to use apt4rpm available on http://apt4rpm.sf.net. Simply install as user root on a command line the necessary RPM packages for your distribution using rpm -ivh packages, then edit file /etc/apt/sources.list so that suser-rbos is in the list of sources. Now after calling apt update, you can simply call apt install MPlayer-suite to install MPlayer and all necessary packages including DeCSS with one single command. The same way you can install most of the tools for video processing. If you need a nice GUI for apt, type apt install synaptic.
Please refer to paragraf The Copy Protection Problem top read what's the easiest way to install software on a RPM based Linux Distribution (such as SuSE or RedHat).
