Earthsoft Bluray DVD Copy does exactly that: it copies blu-ray discs so you can back them up to DVD discs. This works by first burning the blu-ray to your harddrive, then copying that information to the DVD. This is an automatic process from start to finish, except for inserting and removing the DVDs. Serious blu-ray collectors might consider this as a viable method for backing up their blu-ray discs to DVD. With Earthsoft Bluray DVD Copy, quality is guarenteed whenever the blu-ray disc you copied is in good condition. When the copy is finished, you can have it setup to shutdown automatically which is useful if you're going to leave it copying while you are out of the house or going to sleep. Overall, Earthsoft Bluray DVD Copy is a good tool for someone who wants to backup their blu-ray discs to DVD discs instead of other blu-ray discs or to the harddrive.
