Copying DVD to Blank Disc on Mac Mini M2

I was able to find:

"No, iMovie doesn't support DVD video, so you can't use it to copy a DVD to a new DVD. However, you can convert the DVD's contents to a computer file and then burn that data onto a blank DVD. This process is known as ripping. 

To rip a DVD, you'll need: The original DVD, A new disc, A computer that can play DVDs, and A video converter program. 

You can use a video converter program to "rip" the digital content off the DVD and turn it into a video file, such as an MP4 file. There are free options online, but better options may come with a price. 

You can also watch this video to learn how to import a DVD into iMovie:" https://www.youtube.com/watch?v=Bna7cmx7OEg&t=63s

If you're talking about a home video DVD, I believe that you can use Disk Utility to create a .DMG file containing an image of that DVD. You can then use the Finder to burn the image to blank DVD-Rs – creating extra copies of the home video DVD.

This used to be a way to get around the issue that iDVD took forever to create a DVD-Video disc – most of which was spent transcoding source materials to MPEG2 format rather than actually burning the disc.

You can use an app like Roxio Toast that will make an exact copy with an attached DVD drive.
