DVD Ripper for Mac iPod(iPod touch, iPod nano, iPod classic),iPhone, Zune
If you’ve got a 6th-generation iPod (iPod touch, iPod nano, iPod classic) an iPhone, a Zune or some other players, one of the things you probably want to do is put movies on it. After all, movies really do look great on the iPod, and it?s a lot easier to carry around than a laptop or portable DVD player.

The problem is that commercial DVDs are copy-protected, which means you can?t ?rip? them in iTunes as you can a music CD. So you need a special tool that removes this copy protection as it extracts the video content; if that tool can then convert the video to a format suitable for playback on your iPod, iPhone or other players, even better. (And by the way, I?m not talking about movies you?ve rented or borrowed; I?m talking about movies you actually own.)
My favorite tool for accomplishing this task is iSkysoft DVD Ripper for Mac .
