Whenever it comes to download free software, you must always keep some major drawbacks in mind which you may observe in it. When you buy a complete package, it contains a lot of accessories in it which are used to run the software. You may not find them in the free or pirated version. So I would definitely say that a free version of Mac DVD ripper would not have both, complete accessories like user manuals and CDs and neither will it have complete conversion features inside. Before downloading you might see much spam reviews so I would suggest you not to take them seriously.
When it comes to software, especially a DVD ripper for Mac, I would obviously suggest you to purchase the full version because this is very useful software and you would not have any problem in using it. According to some users, Mac DVD ripper is very difficult to use for the beginners but if you have a complete version, there is a user manual to guide you throughout. Moreover, there may be several interruptions between the conversions as the software would not be registered. Although some people provide you with the license key but they rarely work.
There are many formats for video files when you convert them from DVD file. A pirated version might not provide you with all of them and the major ones might not work properly. This will force you to reinstall the software and this will be very inconvenient. If you buy an original Ripper for Mac, they give you the guarantee of video conversions without any interruptions as the files are complete and the software is registered. Moreover, a registered and original Ripper would convert the video files more quickly.
Another matter with the free version is that they usually provide a poor quality ripper. This might result in poor quality videos and the audio and video would become unstable. In some cases, the conversion freezes. Free version usually does not convert protected DVDs properly and would cut the half of it. A purchased and registered ripper would convert any DVD, no matter how strong or protected it might be. Just imagine if you would have any problem regarding the software, who would you ask for help? When you purchase a ripper, they provide you with an easy manual which contains help regarding any thing. So I would suggest a purchased ripper, especially for beginners. Well, you can still try the free version before you buy it. Magic Mac DVD Ripper can offer a trial version with full features. You can try it for 5 times.
