How to Copy Wii games

I did the Twilight "thing". I have the homebrew channel on the menu (although none of the games work). My main reason for the "hack" was to be able to play copied game disks. None of my PCs recognize the game disks. How do I copy my Wii game disks so that I can use them, and put away the originals before my grandkids ruin them?

'Backups' are not supported here. I can understand that you want to protect your originals, but any info given out can be used by 'pirates' to run illegally downloaded games.
