I have tested dvdwizard with the versions mentioned on the Prerequisites page. Those should run without problems.
If you have a version prior to 6.2.5: This won't work. dvdwizard relies on some new options that are introduced in IM 6.2.
For younger versions: Yes, maybe. To put it in other words: You'll have to try. ImageMagick is known to change rapidly and not having the best backward compatibility. So it may work but also it may fail. But either way: Be sure to report your experience in the dvdwizard-users mailing list.
