Cleaned up and corrected version of the procedure found at
http://avidemux.org/smf/index.php?topic=3570.0HOWTO Convert a video in Avidemux for set top DVD playback (create a DVD- Video disc)
Run Avidemux (GTK+ version)
File -> Open and select the video you want to put on DVD.
If you get asked, whether you want the MPEG file to be index, select "Yes".
If Avidemux asks for a "special" mode to process you file (this may happen with H.264 encoded videos), choose "Yes" again.
If you want to append additional segments to your video, use File -> Append for each file.
The next step is only required, if your input video is neither 25.00 (PAL) nor 29.97 (NTSC) frames per second:
Manually change Video to DVD (lavc)
Click the "Filters" button (both on the left side of the main window).
Choose "Resample fps" filter from the list, add it by double-clicking
Enter the new framerate (either 25 for PAL Europena DVD, 29.97 for NTSC North American DVD ),
click OK and exit the Filter Manager.
The next step is required for all videos:
Choose Auto -> DVD from the main window menu.
Set "Source Aspect Ratio" according to your input video. If your input video was intended for playback on a computer, it's aspect ratio will usually be "1:1". If it was captured from TV, the aspect ratio will ususally be "4:3". Next set "Destination Aspect Ratio" to 4:3 if you want to create a normal DVD or to 16:9 if you want to create a Widescreen DVD.
Click OK.
Avidemux has now configured all the settings as required for Video DVD, so don't change anything from now on, except the settings mentioned here. You can go to Video -> Filters in order to check that all filters were set up properly.
If the "MPlayer Resize" filter is involved, I prefer to change the resizing methode to "Lanczos3", which should give a sharper picture.
Exit the Filter Manager and pick Tools -> Calculator.
This step is very important to make sure that the resulting video will fit on a DVD media:
In the Calculator window set Format to "MPEG" and Media to "DVD5" (for 4,7 GB Single-Layer DVD Media).
Don't change the Audio Bitrate, just click the Apply button and close the calculator afterwards.
Click the Video -> Configure button (dropdown on left side of the main window). You will now see that the Video Size was already set by the Calculator.
It's not recommended to change anything here, except the Aspect Ratio. Make sure you set Aspect Ratio according to the "Destination Aspect Ratio" selected at the beginning.
Then click OK.
Click Audio (dropdown on left) -> PCM (or LPCM). This step ensures the re-encoded video+audio stays in sync. When you author a DVD with DeVeDe or DVD Styler, the authoring app will re-encode the audio back to Dolby AC3 to save space.
Click Format -> MPEG-PS (A+V) (if not selected already). This step ensures the file container format is DVD compliant.
Finally click File -> Save -> Save Video and choose a proper filename for your video, like
Output.mpg.
Wait until the encoding process is completed.

I like to use DeVeDe rather than DVD Styler for most jobs, here is a HOWTO
