First step, get a firewire card(PCMCIA) or USB video capturing device from those video converter vendor(examples are hauppauge, snazzi, pinnacle etc). Next install the software that comes with the capture device that you have bought. If the device that you bought does not come with any video capturing software, you will need to source for one.
Make sure your notebook has sufficent harddisk space to store the captured raw DV video from your DV cam. Raw DV video file size are quite large. About an hour of DV video might require 8Gb or more. These are not mpeg2 yet and they cannot be used directly to burn into a DVD-video with your DVD burning software unless it is able to do so.
Ensure that you have a sufficently fast notebook processing power so that you can compress the DV video in real-time to mpeg2(DVD). If not, the next choice would be to capture it to AVI(raw) onto the harddisk, then convert it to mpeg2 at a later time(the conversion process is very slow). You can also choose to look for video conversion device that can do hardware real-time mpeg2 compression to go around this problem.
