Your best bet for this would be a SCREEN CAPTURE program, such as
Replay Video Capture.
Since alot of DVD's are encrypted, making it hard to simply BURN them to your hard-drive, this program allows you to select your windows media player, and record the audio/video to your hard-drive.
Check out their free 2 minute demo here:
Replay Video CaptureThe only downside to the demo is - you have to re-start the program each time you want to record two more minutes :(
But over all, great program - I love it
Good luck!
