There isn't a special program that you need to use in order to burn GI files on a DVD. This can be done with almost any burner software that has the ability to perform data burning sessions. You can use Mac Informer's database to find an application that can help you in this matter, or you can use your regular burner.
You should take a look at ExpressBurn. In order to burn your files using this program, you need to install and open it, from the top bar choose Data DVD, add your files by pressing the Add file button, and press Burn disk when you finished adding files to start the burning process.
