A drive that is capable to write data onto writeable blank DVD media with help of additional software. What else.
My DVD Drive allows me to burn disks. I have worked before with DVD Rs and RWs, as well as CD Rs and CD RWs.
Perhaps you have another drive installed also. The XJ-HD166 is a plain reader. Run ImgBurn and see what it reports under "capabilities". NerÃ¶ Info Tool (in case you have NerÃ¶ installed) is another option to find out in case you don't believe us.
