Worse still, the DVD disc, made from plastic materials, is such a vulnerable stuff to be easily scratched or damaged. Thankfully, there are a bunch of open source DVD ripping programs designed to liberate your DVD movies from the plastic cell and make a digital copy of DVD movies to be playable on any handheld device at your willing. Below are the best open source DVD rippers working under Mac and Windows based on your nominations.

Second Must Mention Open Source DVD Ripper is Handbrake
OS Platform: Windows/Mac/Linux
Yes! How could we leave out the world-famous free DVD ripper Handbrake? It's seemingly that we're accustomed to rip DVDs with this open source DVD ripping program, for the majority of us learn to rip DVDs started with Handbrake. It has a long story in DVD ripping field. Though we have deep feeling about this sophisticated DVD ripper software, we have to admit it has a long way to catch up our needs currently. Cuz once we apply it to rip the latest encrypted DVDs, it will appear various problems, like Handbrake can't rip 99 title DVD, Handbrake fail to find out the valid source, video audio out of sync in Handbrake, etc. All these Handbrake problems result from its inability in DVD copy-protection removal.
One more thing to note is that Handbrake is only able to convert DVDs to MP4 and MKV, with support for iPhone, iPods, PSPs, Apple TVs, PS3s. So if you are holding a latest iPhone iPad or Android, Microsoft device, you are suggested to look somewhere else.
This Free DVD Ripper You Should Not Miss-MacTheRipper
OS Platform: Mac OS X (10.7 or earlier version)
No surprise, another excellent DVD ripper open source is the Mac-based MacTheRipper, which works as quite a beast in DVD copy protection breaking and DVD movie content ripping. To be specific, it can skirt the majority of DVD encryption tech and rip DVDs to VOB file format. And if you are in demand of converting DVD to other video format like MP4, MOV, you need to seek help from the third party.
Warm Prompt: this free DVD decrypter has a little bit low frequency in software updating. It contributes itself only on Mac OS X 10.7 or earlier version, so in case you update your Mac OS to Mac OS X Mountain Lion or higher version, resorting to MTR alternative sounds good.
Shining Star in DVD Ripper Open Source Kingdom-DVD Shrink
OS Platform: Windows
Another alternative DVD Shrink halted development back in 2005, but this shining star isn't forgotten by its loyal Windows fans. Dozens of DVD Shrink lovers recommend this free DVD ripping software to me, insisting it's worth a place in this list. So I invite this open source DVD ripper tool and have a general review on it. As the former info mentioned, it stops updating since 2005, which means its once-powerful DVD decrypting ability falls behind and is powerless to get rid of the latest DVD protection tech. To test its decryption skill, I give it a shot with the latest DVD Big Hero 6, Into the Woods, Taken 3. The conclusion I get is that I ask too much from it and I should not blame it for its inability.
But I have to say when it does work (certain purchased DVDs), it works amazing and generates small files that are great for portability. And another strength lies in its compression, which will compress your DVD movie to suitable file size and you are hard to find any decline in movie quality.
Voice from MakeMKV Fans-This Free DVD Ripper Open Source Worth a Seat
OS Platform: Windows/Mac/Linux
Last but not least, MakeMKV joins the list of impressive free DVD ripper software because of its extraordinary capability in quickly and easily rip Blu-ray discs and DVD to MKV files in high quality with a single click. And it's also famous for its cross-platform performance that it's compatible with Windows, Mac and Linux.
Certainly, it's not perfect. Two drawbacks you need to know: One, it's acclaimed to be friendly with Mac OS X Mavericks or Yosemite, but the truth is that it causes crashes but nothing. Two, the functionality of this free DVD ripper tool to rip DVD discs is free and will always stay free. Yet, the features of Blu-ray decryption and processing are only free for 30 days. After the 30-day trial, you may have to pay USD $50 to purchase a registration key to continue using its function of ripping Blu-ray discs.
Nothing is perfect, indeed. The above open source DVD rippers are of no exception. And it's quite irresponsible to say which one is the best. What I can say is that the most suitable one is the best one for you. So case by case, if you look for a free DVD ripper software with cross-platform, Handbrake and MakeMKV are strongly recommended for you. For those guys who wanna get a solid free DVD decrypter yet ripper on Mac, MacX DVD Ripper Mac Free Edition is second to none. And supposing you are the one who prefer the PC DVD ripper freeware with video compression feature, go to DVD Shrink and it wouldn't let you down.
