does it have a firewire on it? if so id guess you edit shit the same way with miniDV with the whole capturing deal.
if not it should have a usb cable with a slot that looks like this (right):
you could plug that in to your computer and it will recognize a mass storage device and you could copy/paste the clips from the dvd that way. im not suer how those cameras work but this is just what i think and its worth a try
put the dvd in, open the folder for your dvd drive, drag and drop the video file to somewhere on your hard drive (such as "my videos") and then open editing software, locate file on hard drive, and have fun.
