Do you mean data disk only for files or VCD? What exactly do you need to convert? Is the DVD a movie or a DVD game installer? Cos if it's a DVD movie better if you make it into a DVDrip. DVDrips are playable on the computer (installed w/ the right codecs) And playable in DIVX enabled DVD players.

^ Hmmm sad to say I don't think that's possible. I mean to convert your DVD installer exactly like CD game installers. However you can use [b]PowerISO[/b] or [b]MagicISO[/b]. These softwares can make an image of your DVD, and compress it. And then you can burn them to regular CDs.
