I recommend
www.dvdrhelp.com for more knowledgable recommendations than you'll get here.
It depends on what you want to do. You asked for "DVD Burning" software. I'd recommnend Nero. It allows you to burn DVDs.
If you are looking for DVD-Video
Authoring software, to make DVDs of videos on your computer (captured from a camcorder or other source), I'd personally recommend Sony "Movie Studio + DVD". It's not particularly easy to use, but it's not too bad. The only other software I've tried is Pinnacle Studio which is the most buggy unusable mess I ever wasted money on.
