Currently, consumer grade blank dvd's can only hold 4.7gb of data. The average movie alone is prolly around ~5gb, plus menus and extra scenes, which are usually another 3gb, meaning that consumers have to downgrade the quality of the dvd to make a backup of it. In the spring[hopefully
], they will start producing dual layer blanks, which can be burned with a laser, which can hold almost 9gb of data. As of now, the only dvd's that can hold that much data [known as dvd9's, can hold approx 9.5gb] are commercially made, and are "stamped" together. I dont exactly know how they are "stamped" but I do know that they are not burned with a red laser like a cdr or dvdr.
the format will be coming from the "+r/rw" alliance, meaning hp and phillips and a few other brands will be leading the way in producing hardware that burns the dvds. verbatim will be leading the way in making blanks.
dvds are stamped using a similar process with CDs.
a negative image of the master CD is made then they use that to "press" or "stamp" the CDs
