@rooeytoo digitizing what @mowens is stating is completely legal.
Judges have determined that consumers have a right to copy a purchased DVD for their own use—say, for backing it up to another disk or perhaps watching it on another device, such as an iPod. That’s the same “fair use” rule that made it legal to TIVO, DVR, tape television shows for watching later, perhaps on a different TV.
The legal issue is when you duplicate for distribution or copy for profit.
