Avi to DVD with ffmpeg and dvdauthor

sudo apt-get install ffmpeg dvdauthor

Normal screen:

ffmpeg -i film.avi -aspect 4:3 -target pal-dvd dvd.mpg (or ntsc-dvd)

Wide screen:

ffmpeg -i film.avi -aspect 16:9 -target pal-dvd dvd.mpg (or ntsc-dvd)

Make dvd files without menu in a dvd/ folder:

dvdauthor -o dvd/ -t dvd.mpg

Just add several movies this way
File the movies before burning in /dvd :

dvdauthor -o dvd/ -T

Burn:

growisofs -Z /dev/dvd -dvd-video dvd/

A rewritable will be erased automatically.
Here is a script to somewhat automate this process, read it and make sure the settings are the way you want them, to make it executable save it as whatever.sh and do

chmod +x whatever.sh

to make it executable.
Run it as:

./whatever.sh /path/to/file_to_run.

I tried it and it seems to work fine with single files.
