Consumer burned DVDs and CDs are not very harty. Commerically pressed discs
not only have the data stamped in to the recording layer, but also have a
second layer of polycarbonate over it. Consumer burned discs record the data
using a dye layer which is highly affected by light and air. The second
layer of polycarbonate is also replaced by a layer of laquer which isn't as
durable.
In the end unless you handle consumer burned discs with kit gloves they
aren't going to last anywhere close to how long a commerically pressed disc
will. Even if you don't ever touch the consumer burned disc it will fail
pretty quickly because of the light and air oxydizing the dye layer.
CDs and DVDs (consumer burned ones) are very temporaroy storage. They will
not last anywhere close to the 50 to 100 years or more manufactureres
claimed early on in the adoption of the technology. Even commerically
pressed ones won't make it that long.
