DVD Lifetime?

DVDs are lab tested to last about 100 years. If handle poorly and not kept in the cases sitting in the sun or getting wet will start die within 20 to 30 years. I have CDs from the early 90s that are still working today. I also have one of the first DVDs and that still works today.

From what I read, thats gold discs not silver ones. Silver was about 30 years for well produced ones. But this is all lab conditions, nobody knows how long they'll last in real life properly, as we've not been making them long enough!

Wow, apparently DVD rot isn't real. The only way a dvd can die is either a.) it is well over 30 years old or b.) there is a manufacturing defect or you didn't care for it . Hmmm, that makes me feel a lot better about this.
Sosseres:
Manufacturers claim that CD-R and DVD-R discs have a shelf life of 5 to 10 years before recording, but no expiration dates are indicated on CD-R, DVD-R, or DVD+R packaging, nor are there published reports of tests to verify these claims. Still, it would be prudent, in light of these claims, to purchase new discs as they are needed rather than to order large quantities and stockpile them for future use.

Isn't it that when you buy a DVD box set. Those DVD's have a much longer life than ones that you have burned yourself. I believe the "stamping" process that manufacturers use is less likely to cause data loss than burning.

What I posted was time from production until burning. Longer times would create problems with recording the data if I understood it correctly.
