Não completamente alinhada, mas uma maneira de fazer isso :
Open DeVeDe from the Ubuntu Menut at: Applications > Sound & Video >
DeVeDe
Select "Video DVD" from DeVeDe's menu.
To name the DVD title, click the "Properties" button, in the "Title"
section. I like my videos to reply after they're done, so I select the
"Play First Title" option. Click the "OK" button
In the "Files" section of DeVeDe, click the "Add" button. A window
will pop up. Under the "File" section click the folder icon (on the
right), and navigate to where the AVI file is (that you created
earlier using Avidemux). Click the "OK" button. If you want to add
additional avi files, you can repeat this step as needed.
Under the "Menu" section, I always uncheck "Create a Menu with
Subtitles", because I like the DVD to just start playing when I put it
into my player (without the additional that a menu offers).
Now click the forward button, and choose were you want your DVD Iso to
be placed on your file system.
