4Media DVD Ripper 

This program was created for Mac users who need to easily rip their DVDs. The application lets you choose from a wide variety of media formats that are compatible with dozens of media gadgets (tablets, smartphones, etc.) and Mac utilities.

You can use this app to extract the video content from a DVD folder or an IFO file within your Mac. The program features two separate panels for configuring the output settings (Basic and Advanced), hence anyone can easily get the job done with this utility, even without much experience in video editing.

This utility also preserves subtitles and input quality (both audio and video), allows you to preview the imported movie before converting it, and provides you with results you need within moments.

However, the developer provides you with 2 more variants of this DVD ripping tool (Platinum and Ultimate) that give you access to additional features, such as the ability to edit the imported movie before conversion, compare the original video with the altered one, etc. Still, they are more expensive than the Standard version of the application.

In conclusion, it's up to you to decide which of the aforementioned variants it's the best choice for you. If you ask me, the Ultimate version of the 4Media DVD Ripper app is the one that is definitely worth buying.
