VLC player is a free and open source media player, streamer and encoder supporting many video files as well as DVDs. This guide will mainly focus on introducing its capability of converting DVDs on Mac OS.
Insert your DVD and run VLC Player. Then under Media click on Convert/Save.
The Open Media Window will appear and you want to click on the Disc tab. Check DVD, make sure the disc device field points to the optical drive with the DVD, and hit Convert/Save. You can select the start position by selecting the title and only record a specific chapter on the DVD.
Click "convert /save" then a windows will pop up where you are allowed to select a location for the ripped file.
While you are browsing to the location to put the ripped file make sure to give it a name and a supported extension.
Conclusion: Overall, VLC is powerful in both video playing and streaming. But since it is a player at first, it has inevitably limited the range of input and output formats. Also, VLC does not support the DVD with internal encryption, which has also restricted its capability of processing the DVDs.
As an alternative to rip DVD, you can try DVD Ripper for Mac. While VLC Player is a player first and converter second, DVD Ripper is professional DVD conversion tool that does good at ripping DVD to VLC, MP4, MOV, AVI, etc. It supports a wide range of video format, media device, great output quality, etc.
Note: If you are using Windows and want to Rip DVD to VLC Media Player, you can refer to DVD Ripper for Windows.
Then, just insert your favorite DVD on the DVD-ROM and load your DVD files to DVD Ripper for Mac through "Load DVD".
Select output format from "format" drop-down list. Go to "Output" to set the output directory to save the converted files.
When the settings are done, click the Convert button to start DVD conversion on Mac OS X. The Mac DVD Ripper could handle the rest of all for you. If you are busy, you can set "After the video conversion shut down my computer."
