It sounds like you are new to this. Hey, we all started at the beginning. But I think that it would be impractical to try to answer that question on the forum, because it would invariably lead to other questions.
I think you need a book to go to; and as Steve mentioned, and linked to, he has a book that I think would be very good for you.

In general you just drag your movie (called a title) onto the menu background -- this creates the button link, & imports the video. If you have separate audio, & if the files have the same name [test.mpg + test.ac3 for example], DVDA will import it for you as long as it's in the same folder on your drive as the video. Then check the properties for your project, & the Optimize window from the File Menu -- to see if anything needs re-encoded, & you can prepare or burn a very simple DVD with menu. TO skip the menu entirely, File -> New -> Single Movie.
Everything else in DVDA is refining that process. Your menu, which is a mpg2 video, can be done elsewhere & imported, or you can use DVDA's tools to place graphics & text, & DVDA will create that mpg2 for you. There's absolutely nothing wrong with that, & they do save many people time, but learning & using those tools can be confusing, takes longer, takes more learning, & most importantly, often doesn't look as good as what you can do in Vegas for example & import.
It's harder to learn about video DVDs than most other formats because the companies that came up with & own the spec keep *VERY* tight control over it. Copies are very expensive, if/when you qualify to buy it, & requires an NDA so you can't tell anyone else how they work. The only way to really learn DVDs for most folks is to spend some time on-line at sites & in forums where they have reverse engineered them... That way you can become a chef, rather than just a cook's helper following exactly some recipe. ;-)
That said, if you are looking just for recipes, books on DVDA & the manual plus the help files can help. You'd also do well to go through or search old forum threads -- quite a bit of details and many, many guides have been posted here over the years, & if it seems dead now, I assume most of the old pros either moved on or gave up saying the same things over & over. ;-)
Thanks for the help. I will get the book and look at the website for help. I have never used a forum before. When you are old you just don't think about these things. I am a photographer I know about that so this is not what I know. Thanks Again
