What DVD related software needed for Dell + W2K?

Newbie who has a new-to-me C610 laptop with a combo Toshiba R2102 CDRW/DVD unit.
There was no software included for it…any clue as to what would have been supplied with it? I suspect an OEM vers of winDVD but have no clues exactly…I believe I need something like that to make use of the DVD, true?
