DVDFab works well too, although I believe you need the full version
The latest versions of DVDFab actually have a cell phone option built in for ripping movies specifically for a cell phone. It works really well from what I've seen and DVDFab has all the latest algorythms for breaking into the high encryption levels encoded into newer dvds' VOB files
EDIT: Here's the website:
