Step 1. Copy DVD on your computer
The first step of how to edit a DVD is copying the file you need on your computer.
To copy the files, load the DVD into your disc drive and open it in a window. On a Windows computer, go to Control Panel and then Computer. On a Mac, it appears on the desktop.
Locate the main movie file (the largest file on the disk) and drag it to the desktop to copy it. If the disk has several movie files, drag them all.
You can also download a free DVD-ripping program to create digital copies of your discs.
