Hi Folks,

I did something wrong and I hope someone here can tell me how to avoid this mistake in the future.
I have a movie with three audio tracks - Italian, English and German.
The movie is in .avi format.
When I play the .avi file in VLC I can choose which audio track I want to hear.

I attempted to turn this .avi into a DVD to play on my TV.
I succeeded. The DVD plays just fine. The problem is that the audio is only in Italian.
I would really like the audio to be in English.
Does someone know what I should do in the future to set the audio track to the correct (or provide a choice from multiple) language on the finished DVD?

Below are the steps I used to make the DVD:

Code:
1. Convert videos to proper mpeg format


./ffmpeg -i source.avi -aspect 4:3 -target pal-dvd dvd.mpg


2. Add the mpeg to the DVD project using dvdauthor - add multiple files after each file name


dvdauthor -o dvd/ -t dvd.mpg




3. Make .iso file


mkisofs -dvd-video -o dvd.iso dvd/


4. Burn ISO


growisofs -speed=2 -dvd-compat -Z /dev/dvdrw=dvd.iso
