"Simple digital video and still image recording is here with the DCR-DVD105 DVD Handycam® camcorder. It’s simple because Sony has created a camcorder with easy-to-use features, and you can record directly onto DVD.

DVD-R, -RW and +RW Compatible
The DCR-DVD105 is compatible with a variety of DVD formats allowing the ease of use and simplicity found in DVD Media. With DVD+RW media there is not a need to finalize the disc (minimum recording required). Simply remove the disc and insert the media into a compatible DVD Player.

DVDirect Compatibility
The DVDirect Multi-Function DVD recorder models MC3 and VC30 offer direct connection to the HDD Handycam via USB 2.0 and can record all the video on the hard drive to DVD or just what’s new and changed since the last DVD burn. What’s more, the video can be recorded from the HDD Handycam to DVD at up to 3X speed."
(This last point is useful if you're recording at home, for example.)
err so in conclusion: buy that "bad boy", buy the right DVDs for it (I suggest Memorex for its consistency, but ask the sales clerk that's helping you for his/her advice on good DVDs, too), JAM IT IN, and then record~.
