If it's a mini dvd..... you don't need a usb cord. MINIDVD
If you have a mini dvd camcorder
.
You will have to finalize your dvd in the camera and then put the dvd in your computer's DVD burner (top loading only) and then you will have to convert the files (I downloaded http://www.squared5.com http://www.handbrake.fr/ file converter free) and import them into your editing program. Use the HELP feature in your editing program to learn about editing. Usually you would import your videos and drop them in to the timeline, add transitions, menus, music, etc. Once you are ready to burn, your project will be burned to a different DVD and you can file the original away.
