Up until the 28th October, you can get a copy of MacX DVD Ripper Pro for free, using the code BD-TGTXUVYO-OONQRP. As the name suggests, the program allows you to take a DVD and copy it to your hard drive. It also allows you to select various output formats and has presets for the iPod, AppleTV and so forth.
It seems like a good package, although I still prefer Handbrake which is free, open source, and has more options, including support for the Matroska container format (which has great subtitling support and is the basis of the new WebM format).
