You can have a try this DVD Video Converter, which I'm using to convert video format.
It supports so many devices and video formats, such as: iPod, iPhone, PSP, Zune, Xbox, Nokia, avi, wmv, 3gp, mov, flv and more into avi, mov, asf, wmv, mp4, 3gp and others.
It can help copy whole DVD to your hard diver or convert whole video to any devices:
