The next versions of Transcode and ImageMagick had required some patches to dvdwizard. And Joachim Wiedorn (aka "Joo Martin") added some options: -W to define pause, -ar to change aspect ratio for each titleset (4:3 or 16:9).

The current version 0.5.6 (Feb. 2009) works with ImagMagick until version 6.4.9-6 and with Transcode until 1.1.0. All versions you can found for download under sourceforge.net.

You can look to the changelog to all changes of dvdwizard.
