Hi Sue,
Ok prepare to start learning!!! You need a Firewire connection from the camcorder to your PC. Check this thread out first to get an understanding of it all. You will need to use some software too, which if you are using Windows XP you may well be able to use Windows Movie Maker, which is in XP.
Camcorder and video editing Frequently Asked Questions
If you need a firewire (also known as IEEE 1394 or i-link) then you can get a PCI card and cable from around £10 in certain places....including from me at a last resort!! I have a few brand new spare ones around....
It all depends on what you want to do wit hteh video footage once you have it on the computer to which software would be the best for you. DO you want to do some editing and then burn to DVD to share your son's movies for instance???
Ok enough for starters hope this helps get you started!!
