I can't remember where I saw this, If I find it, i'll post the link.
But anyways, you can buy basically self contained DVD burners in a tower(approx. 5-10 different drives), from this, you plug it into your computer, and following software Burn all these DVDs at once...
Its basically the same way CD's get manufactured, Just with DVD's and on a much smaller scale.
they come out with that Silver bottom, so it looks like its a real DVD/CD, rather then the blue.
Try Googling DVD burners, or DVD manufacturers... might have some links somewhere.
Your post made sense, So don't worry.
