I've had a DVD burner for almost 3 years now, and I still have DVDs from the 25 pack of blanks that I got with it... I rarely use my DVD burner, because it's my only DVD playing device most of the time, I have poor disk storage, so backing up enough info that DVDs would be needed is a rarity for fear of losing said data. The only thing it's been used on is Windows XP 9-1 disks, black edition disks, Vista disks, etc.
