HandBrake

Handbrake is a tool for DVD archiving that combines applications like “Mac the ripper” and “MPEG StreamClip” into one app. It uses a large set of opensource encoders that enable you to create MP4, MKV(with subs, multiple audio) AVI or OGM(also sub and audio tracks). The usage is very simple and it comes with allot of preset output configurations for popular devices (iPod, iPhone, appleTV, psp, ps3).
