How to backup from DVD to my iPhone 5c?

Everyone has some important contents on DVD or other device. So I need to watch the content from time to time. I need more details about how to do it. Can you give some advice on it?

[NB: This works for me, via windows to android. Is not shure if its that easy on an iPhone ]
If its a video or file you have, you can easily just drag the video/ file in from your DVD onto your desktop. From the folder from the DVD to you Desktop by pressing ctrl+c ( copy ) then press ctrl+v ( paste ) when you're on the desktop.

-Then pug your phone into your computer via a lightning-cable.
Go to computer>( your phone name ) > internal storage, and paste the video / file on that folder ( internal storage).
