i need to make a copy

#1. i need to make a copy of my pc game disc (star craft broodwar) i just need a back up how do i do this?

#2. i have a dvd burner i just have no idea how to use it... how do i copy a dvd to my pc or to a DVD-R

that would be impossible, and its also copyrighted infragment.

not to sell to back up you can do it as long as u own it my greind made a copy of his age of empires cd

Use Nero.
Its fairly easy if you have nero.
Get Nero 6.0+ the highest one their is.
DO NOT GET NERO 7.0. Its just a useless demo....
believe me, its really easy to copy it.
Does this game require a key?

no and if it dose all the disc i need to copy is a play disc its needed to play and its starting to get beat up and wear cn i get nero?
