Burn AVI file to DVD on Linux

"Use Avidemux (Available for Linux and Windows).

Detailed video on converting to DVD format here. You'll also want the DVD authoring guide."

If your AVI file is encoded in Divx or Xvid you might want to try burning just the file. DivX playback is a popular feature on DVD players these days... yours might support it without you even knowing.

Try Handbrake

"Not completely stream-lined, but a way to do it:

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."
