Easy enough
First update all of your video and audio codecs on the computer you want to use. Some places I remember are CCCP and Divix or DivX something like that.
Now your computer may recognize the DV connection in web cam programs like Manycam or Tracker Cam there are several.
If you want to record go to Media program like Cyberlink Power Director, sometimes MS movie maker, Typically you have to go in the program and tell it what device you want to capture video from and your device should be there if its plugged in and turned on, via whatever connection you use.
Most of these came with your computer or are avalible as freeware. The trick is finding the right combination that works for your equipment. I have a different set of programs that only work for the specific video source I use (DV, Analog, through Capture Cards/Devices, etc, USB, Firewire) I have not found one program yet (free anyway) that works with all devices. Some even recognize the device but for some unknown reason will not show the picture. Trial and error is the only way I have figured it out.
