Has CD Quality Control Slipped?
morris57 asks: "In the past few months, I have had at least 3 brand new compact disks or DVDs not work right out of the box. I don't mean that any sort of copy protection on the disk prevented me from using them; they were simply defective disks. I was able to exchange my DVD of 'The Matrix Reloaded' at Best Buy for a working copy, but some disks I got for Christmas I just recently opened and they are either unplayable or garbled. It is not a hardware issue, either. I've tested the disks in several types of players: new, old, component, computers, etc... It seems to me to make a very good case for downloadable media files, although I know these tracks are not available on iTunes or audible.com. So, I guess I'm wondering if the Slashdot community has noticed a decline in quality control of CDs/DVDs. What can be done (individually or communally) to not get burned by defective disks?" The solution for this particular type of problem boils down to simple consumerism. If you get a defective product, return it! If manufactures notice a high rate of return (and they should), they'll hopefully address the quality of what they ship. Has anyone else noticed an increase of non-working DVDs or CDs?
I've only had one new DVD ever have any issues. That one DVD would freeze up at one spot, but it only did it on one DVD player. I suppose that it's probable that manufacturers are taking more and more shortcuts, but I haven't been affected by it yet. I hope it stays that way too.

Sorry man, it's not the disc. Back Street Boys really do sound like that, no matter how many times you return it.

...this is quality control. That latest Britney Spears CD sounds bad for reasons beyond the scope of QA.

Returned it for the other copy of "Emergency" in-store, and asked to listen to it before I left. Sure enough, it was also actually "Change." What a pisser.
I bought a 100 pack of Philips CDRs and I thought it was a freak case - perhaps it is not.
Almost 30-40% of the disks scratched easily, and didn't work after 2 months of safe storage. They seemed to develop scratches for no reason at all.
I have read that the normal life expectancy of a CDR is about 2 years, in my case, the life expectancy seems to be 3 months.
Note: Other brand CDRs bought more than 2 years ago record just fine, and have survived for 2 years or more.
Has anyone else seen this trend? Cost cutting perhaps? I know that CDR manufacturers are experimenting with cheaper variants of pthalocyanine to get more bang for the buck.
I haven't noticed it with [C|DV]D's personally, but I have had problems in the past with electronics I purchased around the holiday season. My guess is that on occasion a manufacturer will push manufacturing beyond what QA can handle in order to meet demand at the end of the year. The only choice is to return, of course at this time of year the manufacturers expect high return rates so it might not make a difference.

The video portion stopped while the audio continued. Took it back to the store where I got it, the manager took it back to the back room and I told him where it happened. He repeated the problem on his machine. Then he got a fresh one off the shelf. Same problem. He gave me credit for the disk and I had to take a different title.
So, is quality control slipping? I don't think so, as this was 3 years ago.
I've deffinately noticed HUGE issues with DVD's.
I rent probably 3 new DVD's a week on average, and without fail, one a week won't play in either of my players (Component and PC).
Brand new discs, very often the very first use of the disc no less.
I've also noticed that looking at the edges of the disc, that they are way less than perfect. Usually the layers don't line up very well, there's usually a very obvious seam, sometimes even with adhesive squeezed out the edge. I'm thinking super cheap-assed production.
I haven't noticed similar problems with CD's, although I've almost entirely stopped purchasing them because they're almost all NOT cd's anymore.
No Comment.
I also had a problem with Disc 2 of the Matrix Reloaded DVD set. The DVD froze in the same place before the main menu every time i put it in my home theater DVD player, but worked flawlessly in my DVD drive on my desktop.
Has anyone else had this trouble with DVD's not playing on a set-top device, but firing up on a DVD drive of a computer?
There are 01 types of people in this world. Those that understand binary, and me.
My parents got the Indiana Jones trilogy for Christmas. I tried to play Raiders on my laptop DVD player with mplayer, and it froze up after about 1-2 minutes while it was displaying the "Raiders of the Lost Ark" title. I thought it was odd and tried again. Died in the same spot. Odd. Put in my parents' console DVD player and at the same spot everything went blue, sound quit and then after about 2-3 seconds it kept going. Definitely a defective disc. Couldn't convince them to take it back though, they decided they could live with that little glitch.

Maybe your CD/DVD player is getting cranky?

I noticed this with recent purchases of videotapes. The older ones worked fine, so doesn't seem to be the fault of any of my machines. I wondered whether the quality deterioration was intentional to push people towards digital, or just not caring anymore (people left for digital, not the same profit/volume in videotapes). So, I'm actually glad to hear this quality deterioration isn't limited to just tapes.

Hey, maybe it's a conspiracy so people will buy downloaded services
I recently bought a copy of K-19. I went to play it the other day, and the disk inside was actually of K-9.
Yikes, talk about your shock to the system! The store made it right without the slightest fuss.
I back up my Anti-RIAA/MPAA opinion in that I don't buy CD's or DVD's. I have two DVD players that were given to me to try and fix. The are still broke. I occasionaly do go see a movie, but I don't break the bank trying to be a media whore.
Someone hates these cans.
When the extended edition of Two Towers came out, I discovered that the second disc (part two of the movie) was scratched and wouldn't play. When I returned it to the store, the salesperson noted that an unusually large number of people had the same problem with that particular product.
I noticed the same thing with videotapes and floppy discs.
In the case of CDs and DVDs, I think that cheaper material translates into higher flaw and failure rates... as the data has less plastic to protect the data from wear and tear.
Has it occurred to anyone that the machines that use the media also use cheaper parts as well? Portable CD players that I've used in the recent past seem less forgiving of scratches than the big clunker that I owned ten years ago.

I received one of those disks with little brushes attaced to the underside free with my dvd player. So far it has always resolved these little glitches for me.
My mom (silly mommy!) got me Civ II: Test of Time for my birthday. I figured I'd go poke my way through it. The case contained the CD and a note saying that the manual was available online. Unfortunately, the link is broken and there's no sign of contact information, in sight or otherwise. =b

I have had several DVD issues from the very beginning. It doesn't seem to have gotten *worse*, maybe better in my experience. The only DVD I have had problems with lately was Bruce Almighty. You could see the damage on the disc. Not a scratch, but an oval shaped damage within the layers themselves. I have also had a few DVDs that partially wouldn't work in Apex players that work absolutely fine in my Sony DVD players.
Actually I've had the opposite problem of what you said, in that "copy protection on the disk prevented me from using them". I have never had an actual defective disc. I do in fact have often and numerous problems where Digital Restrictions Management always defaults to protecting the content over letting me, the user (licensee) viewing the content I've paid good money for. I'm almost at the point where using an "illegal" (in the U.S.A.) player for that commie, un-American Linux thingy would seem wiser than using a licensed player.
I picked up a bunch of generic 100 packs (yeah I know) and they won't play in the car. previously the same generic brand worked just fine.
This reminds me in the waning days of the floppy. The quality was piss poor, but I have some old "heyday" sony floppys that are still running strong.
I feel like this has been occuring, but I don't know enough about the technical specs of how cd's are made to prove it.
However, in the past 6 months, I have purchased several CDs, and have had to reburn (checks disc box) 4 of them. I've also reburned several of my recent CD-R mix cd's. I don't know why, but after only a few weeks of use, these CD's have begun to skip. I have many CD's that are pushing 10 years old and are still going strong (which is amazing, considering some of them look like I scraped them across pavement.)
For some reason CD's I've purchased recently aren't holding up as well. If anything, I'm treating my CD's better than I used to, I just don't get it.
Are they making the actual data layers out of thinner/cheaper metals? Whats going on? I can't be the only person that's noticed this.

When you burn your own you dont have that issue :p
I bought a DVD recently, and the box was empty. I shit you not. Fortunately the store believed me and gave me another one.
Man, CDR's are so unreliable, its sad! Especially those ones that have no label on the front. And now they cost almost as much per MB as a hard drive (in Canada)... guess which one im gonna buy. Ive found that those CD cases that hold 50 CD's, scratch CDR's enough to render them useless after a few months. Mayby this is a ploy by the RIAA to stop people from buying burnable CD's!
I bought a 50-pack of Sony disks. The first 5 i tried (4 off the top and 1 out of the middle) would not record. After a little bit of arguing, the store refunded my money.
Silence, fools! A is A, therefore I am right!
Unless you pay over $1,000 for a sony product (or $1,200, today, because the dollar is about as strong as the peso, thanks dubya), the quality will always suck.
When are people going to realize that sony is a shit brand. Everything sony has a very limited lifespan.
Once, I had bought the 2nd season of Lexx, and 4 out of 5 discs were totally screwd. Something about the way they pressed them made them corrupt and totally unusable; there were tiny bubbles in the enamel layer that were interferring w/ the diffraction grating (where the data is located).
