I would thing the deterioration of the plastic would take a few million years though.
Poor manufacturing and poor quality. Unlike CDs, most DVDs are imbedded in the plastic rather than laid on top, however, as it turns out, some DVDs are laid on top. The top layer can then corrode and the layered ones can sometimes split. This is information I gleaned from the net.
I cannot see any defects, even with good lighting and magnification. Whether I can see or not is a moot point as the sundry of DVD players I have do.

Speaking of that NEVER buy discs whose layer is black! Trust me, you'll regret you bought them the moment you put them inside the dvd-rom and the devise will spit it out without even burning it.
Nowadays the best discs I've encountered are Maxell's.

I no longer do recordable discs. I archived bunches of stuff when they first came out and lost over thirty percent of the data after only 2 years, yet I have the original Microsoft DOS 6.2 3.5" floppies that are still good. My archive is now an 8TB RAID 10 system.

I've also heard that sometimes, cost-cutting measures lead to certain batches "bronzing" and becoming unplayable. This has even happened recently. Case in point: The Criterion Collection did this sort of thing with some of their early Blu-Ray titles. Let me repeat that: CRITERION (the high-end R1 DVD company) did this on BLU-RAY (the theoretically more durable medium). At this point, I would not be surprised if this happened with the DVDs you bought.
Really, not having access to the actual DVDs, I can only guess.

"Bronzing" is the term for the aluminum corroding and allowing the silver to be exposed.

And I just got another hit. This one was a blu-ray. Thanks.  It looks like this one is printed on top rather than sandwiched.

No that's a misconception, DVD simply means DVD.

Sure, those abbreviations just came out of nowhere. The same way FBI means just FBI and CIA means just CIA. Right...

No, it did not come out of nowhere, but the "meaning" has shifted about:

The origin need not be the current use, as in this case.

Maybe so but "Digital Video Disc" is what those of us born before 2000 used to call it and still call it. Mostly because we got accustomed to the old name. It's also easier to remember and pronounce.
