# Quick n' dirty single "movie.mpg" to "dvd.iso" to dvdrw/dvdr disk.
# The "movie.mpg" will need to be a dvd compatible file, eg with ffmpeg the
# "-target" switch will be required with pal-dvd or ntsc-dvd or film-dvd set.
# Script will overwrite rw disks without asking so make sure you have the
# right disk in your drive, in my case that drive is /dev/sr0 yours may be
# different.
# Make the script executable and chuck it in the "nautilus-scripts" directory.
# Usage: Insert a disk, right-click file to burn > Scripts > qd-dvd.
