Well, 2 people already asked me this, and I barely have an answer to give.
My sister and a friend have small kids, who love to play with the DVDs. Some of the kids DVD are hard to come by, since demand is not as high, which brings the question:
Which program can be used to make backup discs of the DVDs?
I know that a couple aren't sold anymore, so I don't know what to recomend anymore.
