Check the list on my website in the "DVD Programs" section.
There are quite a few listed there, including the ones named by the others
who responded to your post, along with links to their websites.
I personally have 2 recommendations.
For the lighter hobbiest I recommend Ulead Movie Factory. It has a lot of
capability and a very user friendly interface and is fairly inexpensive.
If you really want to create things people will talk about then I recommend
Ulead's DVD Workshop 2. This program does everything you could possibly
think of and more but it comes at a price of $300.
There are quite a few others listed on my site to check out and most of them
have free trial downloads.
Beware of googling and downloading the free authoring programs. There
usually stock full of adware and are really simplistic in what they do. (You
get what you pay for)
