Aiseesoft DVD Copy for Mac is a DVD duplication tool. There are a few different ways in which this app can copy your movies. It can create a perfect copy of your movie, duplicating everything from the original disk. Additionally, it can be configured to copy only the main movie title and discard the rest of the content, so that you end up with a smaller movie in size. This mode is automatic, and it analyzes your disk's structure to determine which is the main movie title. If you want to, you can manually select a DVD title and only copy that. If you have a DVD-9 movie, and you want to fit it into a DVD-5 disk, which is way cheaper than a blank DVD-9 disk, the app can reduce the quality of the video to make that happen.
Aiseesoft DVD Copy for Mac is capable of burning your copied movies to blank DVDs, but it can also save them as a DVD folder on your hard drive or as an ISO file, which you can later burn with another utility, or mount it on your Mac via Finder.
The application has a very nice graphical user interface that is very easy to navigate and understand. There are some very concise on-screen instructions on how to use the application.
I like that the app lets you select a DVD folder or an ISO image as a source. My Mac Mini doesn't have an optical drive, so I use Remote Disk to use my Macbook's drive to copy DVD movies, and this app works with that setup just fine.
