what kind of stuff are you burning to DVD. movies,music,data, what? if your going to be just burning data or copying disks and music then programs like imgburn will work. for burning DVD movies you will have to get somthing like nero or anydvd which costs money
another vote for imgburn... best and most complex free burning software out there...
one down side is that you can't burn multisession disks!
you can also try burnaware free which is pretty good... but it's rather limited in option so for a power user I would recommend imgburn.
