DVD Ripper Thing?

Is there any software that someone is familiar with that can burn just parts of a dvd. Say like a 30 sec clip. I am trying to find something but dont even know what it would be called.

Thanks.

DVD Decrypter allows you to selectively decrypt certain chapters from a DVD. After decrypting, you could probably use something like Virtual Dub to cut the clip down to the exact segment you want.

Check out http://www.doom9.net for both utilities.

Thank you very much.
