Need tips for creating digital copy of dvds

Hi, I've got a pile of dvds that I'd like to copy on my HDD in other to watch them on my mac or on my tv through an AppleTV.

I've never done this before, so I'd like to have advice on which software to use, how does it work and what should I be careful when copying.

If possible I'd like to keep all the settings available on the dvd (menu, language, sound settings, etc.)


Thanks
