You may want to convert a video from a variety of formats to DVD, to be able to watch it on a stand-alone, DVD-only reader. DVDs use a quite rigid format. Many user-friendly programs allow you to convert video to DVD format very easily and without having to know video-related aspects. But almost always, the results I got were not 100% DVD-compliant, and, while they could be correctly played in more sophisticated players, they led to bad surprises when moved to cheaper or older devices. It took me much time to correctly tune all the parameters, and I'd like to share this little bit of knowledge with people having the same problems. The solutions I propose here use the MPlayer/MEncoder pair of programs. In addition, some important concepts related to digital video are discussed.

Many people consider Linux as a tough OS, for its software package management is not that easy as in Windows. At my early time of using Linux, I also tried to find a file like setup.exe in Windows. Additionally, when I was using RPM, I was very afraid of the "dependency hell", which asks me to install other packages in order to meet the dependencies. Now, thanks to the excellent job of many open source enthusiasts, we can find a better way to manage software packages than Windows CNR (click and run) style. This article will introduce you the tools, YUM and APT-GET, for software package acquirement and other toolchains to work with them. Distribution specified package management will also be mentioned.
