No, disc bronzing isn't something you get at the DVD tanning salon.

This is from an article in The Globe and Mail (UK) called "The scourge of tape mould and laser rot."

"Think you're safe with all your movies on DVDs? Think again: "Laser rot" can affect old CDs and DVDs. They are coated with an aluminum surface to make them more reflective; the aluminum can oxidize and degrade. "CD bronzing" is a form of this: If your CD isn't playing well, and the playing surface is going brown, it has become irretrievably corroded"

I haven't come across any myself,, usually the discs won't play because of a finger print or other foreign surface substance,, ( little soap and water takes care of that).. If you google DVD ROT there are a number of sites to read from, and even Home Theatre ran a forum post about this. but that was over 4 years ago.

I did come across this gem of a site outlining all these concerns.
In the 60's, People took Acid to make the world Weird. Now the World is weird and People take Prozac to make it Normal.

I had one DVD (out of 1500) and no CD where the mirror layer apparently did not adhere well enough and broke up in small pieces. Not a very old one either, from 2005 I guess.

Laservision discs were worse in that respect, about half of them would not play by the time my last player expired.

You're sure about that? I've never experienced anything, but I do not watch my 5500+ once a year either, so I can't rule out that some discs have gone bad.

This effects mostly cheap blanks where the aluminium isn't sealed by a second plastic layer.
That's why blanks for professional backups (storage time 10years +) cost a lot more than normal consumer products.
It all seems so stupid, it makes me want to give up!
But why should I give up, when it all seems so stupid?

Well, Lethal Weapon 1 and 2 (both German first releases in Snappers as part of a boxset) went bad and I had to replace them with new releases in Keep Cases.

That was a problem that affected a few batches of mainly European releases.

The 1st. batch of Silence of the Lambs UK was probably the most widely spread problematic disc of those suffering from dvd rot.
Most (if nor all) of the defective batches were traced up to a duplicating facility, Technicolor UK (not related to the Technicolor we see on movie credits). The glue they were using to stick both layers of the disc was cheap and defective and wouldn't seal properly after some time, causing air to infiltrate the disc and oxidize the layers.
But since the problem was recognized by several of the studios that commissioned their duplication to Technicolor UK (that denied it was their problem up till the end, even after the studios' disc replacement programs), I haven't heard of that problem appearing again.
With every passing hour our solar system comes forty-three thousand miles closer to globular cluster M13 in the constellation Hercules, and still there are some misfits who continue to insist that there is no such thing as progress.

Yeah, I had that one. There was a similar release of Terminator that went bad also.

Have some 14 year old Verbatim CD-Rs with this problem, but other than a few funky pressed discs that were recalled and replaced never had any major issues with most DVDs.

I'm waiting for my first edition Devil's Advocate to fall apart as that's a known problem disc (something about bad glue causing the dual layers to seperate and render it unplayable). It was still playing a few months ago, although I can see the edges coming ever so slightly apart. I backed up the entire VOB files on my HD and an external HD so when it does die, I can make myself a new one.
If it wasn't for that lawsuit about the statue I could just buy another, but the first ones were scarce and getting scarcer as they literally fall apart.  

The only other disc I ever had die was a porn (The Other Side of Shawnee), although when I moved from a Cyberhome to Toshiba dvd player, it started working again.   Maybe it wasn't dead, but it also failed in my old Sony as well as the Cyberhome and a roommate's Panosonic. Since it still plays (I think, haven't put it in for over 2 years) I also guess it doesn't count as dead. Just dead to most players I guess.

One disc of my Indiana Jones Trilogy is affected. I can see a kind of fog on the disc. No way to remove it. The disc is "stuttering" on some chapters on all my dvd players. I think i have to replace the dvd.

That's a different problem and you should be able to solve it by either just washing off your disc with dish liquid or if that's not good enough cooking it (yes, no kidding, just like cooking noodles).
