How to add subtitles to an avi file and burn it to DVD

I have been battling to find instructions on how to add subtitles to an avi file so that I could make a DVD and watch it from a DVD player.  This forum on VideoHelp.com put me on the right track and I found another way of doing it with free software that I already had installed on my computer.

I used FormatFactory and its embedded help  gave the instructions as follows:

Launch FormatFactory and drag and drop your file into the FormatFactory window.  A window will appear where you can select the output format of the “conversion”.
I left it at avi (‘All to AVI’) since I want the output to still be avi but with subtitles:

Next, click the “Setting” button:


Go down to the “Additional Subtitle” section and then click on the Ellipsis (3 dots) which will allow you to navigate to the subtitle (.srt) file.
Click ‘OK’ ‘OK’; then “Start” button to start the conversion.
Wait for a long time…

Then the converted avi file with subtitles is created and can then be burnt to DVD using your favourite burning software eg: ‘Nero Vision’
