DVD-RW burning

I've added a DVD burner to my system. I'm having no problems writing CDs and CD-RWs. Under Windows, I can easily burn CDs and CD-RWs, but I *HATE* booting back to Windows just to make a data disk that I should be able to burn under Linux. I looked at the X-CDRoast page concerning this, but it only shows versions up to SuSE 8.1 ... and I'm on 8.2. I tried running the version distributed with 8.2, but it doesn't appear to be setup to do anything to DVD's; absolutely can't blank a DVD-RW. k3b describes itself in Yast as a tool for burning CDs and DVDs, but darned if I can find how to do that. What tool should I be using to burn DVDs and DVD-RWs in Linux?
