Since there are a number of other requests for info along these lines,
here's the email I posted to an earlier question on iMovie editing DVDs.

You will need to convert the footage from the DVD into a format iMovie
understands before you can import it.  DVDs use MPEG-2 format while iMovie
only works with the DV format (DV Stream).

Probably the easiest way to do this with unprotected DVD media is using
Apple's Quicktime Pro (and the latest versions of Quicktime which finally
work with MPEG-2). 

1. Register Quicktime Pro for US$29 at http://www.apple.com/quicktime/buy/
2. Enter the Registration number in Quicktime Player
3. Choose Open in QT Player
4. Open the Video_TS folder on the DV and select the first .vob file on the
DVD 
5. Select Export from the File menu
6. Choose "DV Stream" from the pop-up menu
7. Choose your destination and then wait for a while for QT to convert your
footage to DV format.
8. Repeat for all remaining .vob files on your DVD
9. Next import these files into iMovie, and edit them to your heart's
content.

Note that extracting video from copy-protected DVDs (for backup or playback
off HD) needs other tools:
