Ok, Ive been reading the other topic thats about 4 pages long, And I seen that the package has a vacuum seal? So when it comes into contact with oxygen it turns into another color and last 48hours? Also what is inside the vacuum seal? Nitrogen, because i have access to that. Im just wandering on what makes it turn into a non playable dvd. Im gonna stop at walgreens and pick one up, I live in the KC area. Just want to know how it works.

Thanks
