There are a few out there, but something like Adobe premiere elements would probably serve you well. That will take in your dv footage and let you edit,add transitions & titles and then burn a dvd of the finished movie.

There are others like Pinnacle studio and I think there is a cut down version of Sony Vegas as well, best thing is to check out their websites as they normally have trial versions you can download and try and find the one that best suits you and the way you work.
