Creating iso image from dvd

[Rob Wultsch]

The short:
I want to make an iso image of a dvd, using either windows or linux.

The long:
I just bought off ebay a 11 dvd set of all the Daria (an mtv cartoon) 
seasons. My understanding is that this dvd has never been sold to the 
public so I want to copy it. I  (well a friend of mine) has access to a 
mac dvd burner, but it seems that the mac has very little software. I am 
making the assumption that anything can burn iso's. I own a usb hard 
drive that I could use to transport the images.
