Or the government will get you.
I just used random files I had.
You will need Handbrake and MacTheRipper
Now Insert your DVD. Close DVD player if it opens. Open MacTheRipper. Choose Mode, then Main feature extraction. Then click GO!
Now after that is done Open Handbrake (I would close MacTheRipper). Find the file MacTheRipper made, and off to the side choose iPod under Apple. Now fit the Average bitrate to 640, then click start.
(WARNING some movies don't work.)
