Create two files, say dvd.sh and dvdauthor.xml.

If you have, for example, seven .flv files downloaded from youtube as a serial, from one to seven, and wish to burn to a dvd to view with a dvd player... It can happen that not all the files have the same resolution, but try to minimise the work and speed things a little.

Into the dvdauthor.xml you may write:

===========
<dvdauthor>
<vmgm />
<titleset>
<titles>
<pgc>
<vob file="dvd.mpg" />
</pgc>
</titles>
</titleset>
</dvdauthor>
============


Into the dvd.sh file you may write:

=============
#!/bin/bash

echo "Removing contents of Trash"
rm -rfv ./.local/share/Trash/files/*
rm -rfv ./.local/share/Trash/info/*

if [ ! -d ${HOME}/dvd ]
then

# Only make dir dvd if it doesn't exist
echo "${HOME}/dvd did not exist, creating..."
mkdir "${HOME}/dvd"

fi

Rename the files input1.flv... to input7.flv and place all the files in your home directory and a dvd disc into your dvd driver.

Run dvd.sh.
