Blu-ray title suffers coating rot?

Blu-ray title suffers coating rot?
A thread over at AVS Forum has been running for weeks now, discussing what many have discovered; "Blu-ray disc rot". Some users are reporting finding small spots on their discs that render them unplayable, particularly with "The Prestige". However, as it usually goes, many other users are reporting that their discs are still working correctly and do not show the dreaded signs of rot.

It's impossible to use a forum to judge how widespread a problem really is, but in the past, forum posts have lead to product recalls. If you check your Blu-ray titles now and find that the data side seems to be showing signs of rot (picture below), you should seek a refund or replacement disc immediately.

    I said elsewhere that this is God's revenge for them f*cking about & taking the pi*s with that BS about Manchester Cathedral.

    They apologised so it may be limited.

    Kidding aside, wow, just what neither BD nor the PS3 needed right now.

    It'll be interesting to see just how widespread this is.

    Even if it's not the perception of major trouble could do a hell of a lot of damage.

    I think they just forgot to advertise another part of Blu's DRM... open the package and you begin the "rental period", after which your disc becomes unplayable without the purchase of another license, aka disc :)

    It's still early in Blu-Ray's life; as such I bet this problem is related to the printing plants not properly printing the DVD. They'll get the kinks worked out.

    16.6.2007 17:57 #3

  • Pop_Smith

    The problem isn't widespread so its probably just some (really) bad pressed disks.

    If this was more common among Blu-ray disks then yeah I would agree with akaangus and say its the other DRM Sony has not mentioned yet. :-p

    I wonder if something like this has also happended to DVDs earlier in their life or even in the other competitor, HD DVD.

    PeaInAPod and Pop_Smith have good points.

    HD-DVD had playback problems with some copies of Children of Men and The Good Shepherd:

    The good thing is both sides are doing something to rectify the problem and are replacing the defective discs.

    HD-DVD Rule just cause it's not sony's

  • mspurloc

    Damn it! Sure enough, there are pits in two discs. One of them I've never even watched. Just like the early DVDs had, only worse. I bought both formats, so I still have one of each that's playable, but I paid a lot of money for these collector's boxes. There is NO excuse for this. Did they learn nothing from DVDs? Settles it for me. No more middle of the road. From now on, if it isn't on HD DVD, I don't buy it.

  • PeaInAPod

    Yeah but capacity isn't an issue as no current titles today even fill up the disc. If they did menus,special features, and extra audio tracks wouldn't exist.

  • windsong

    Not true. The Black Hawk Down release saw 49 gigs worth on Blu-ray.

    16.6.2007 20:49 #10

  • PeaInAPod

    What I am saying is that 49 Gbs was not just for the movie and the audio track corresponding to its release region. I bet that included " __ # of hours of extras footage", 5 additional Dolby HD audio tracks, and who knows how big those interactive menus get. I am saying Blu-Ray's capacity is a moot point because no movie(not the extras, and not the commentary, but the actual featured film) actually uses the full capacity of Blu-Ray's disc, same goes for HD. Sure the movie studios may use a discs full capacity but that full 49 Gb disc is including extras thats not just the movie.

  • trigga71

    yeah a good point but people buy movies for extras and stuff like that now days. Just like cars with dvd players as long as the kids sit down and shut up they will buy it. Even if it gets 20 MPG or 50 MPG. I have to say on the Cars dvd they used some of that space for a short "film". Im sure many other dvd as well a next-gen media will use this space now that they have the option.

    I believe a good portion of the space in Blu-ray is used as DRM. And well, this seems real funny to hear now considering Sony was being sued on infringing some company's special coating or materials used on their Blu-ray disc recently.

    Edit: I just removed the quotes I used

    17.6.2007 02:11 #15

  • hughjars

    Anyone who wants to know how much actual movie is taken up on the disc can easily see with a straight BD-rip.

    The vast majority are 24gb and under with one or two at 40gb

    (Black Hawk Down for instance is 42.50gb with English PCM 5.1 Surround; English Dolby Digital 5.1 Surround; French Dolby Digital 5.1 Surround;
    Subtitles/Captions - English SDH; English Subtitles, French Subtitles, Spanish Subtitles, Portuguese Subtitles, Chinese Subtitles, Korean Subtitles & Thai Subtitles.
    It also 3 Audio Commentaries & a documentary.
    Basically a ton of 'extra' cr@p other than the movie which would come in at well under 40gb without it,
    It certainly does not 'need' a 50gb capacity disc.

    I'd lay money on it that the same thing would fit on a dual layer 30gb HD DVD disc with VC-1 encoding, easily.
    Even without VC-1 encoding or any changes I'd say it looks like it would probably fit on the new 17gb per layer dual layer 34gb HD DVD disc that is coming soon.

    Of course clunky & "dead" (according to Steve Jobs) Java is also a space-hungry element HD DVD happily does without.

    But as Paramount & Warner's dual format releases show, with a modern & efficient codec like VC-1 you just don't need all that size - or transfer rate for that matter.

    The truth is it was only there to allow Sony to continue collecting royalties on the ancient, almost 20yr old, MPEG2 codec which needed that size & transfer rate to try to look in any way half decent......and usually failed to anyways, the list of poor transfers is almost all BD and in large part thanks to MPEG2.

    It's so bad in fact that Sony now claim they will re-release the worst titles to correct their error(s) - wow, after how many months? That's assuming they actually do & it's not just quietly forgotten.

    But to return to topic.......

    The stuff we're seeing on those discs looks like oxidisation of some kind, I've heard laser disc had that at one point so it may easily be resolved......their problem at this stage is how widespread is it and how badly will it affect their brand as news of this spreads.

    - What lies?

    It's true that the list of real stinker encodes is (with one exception) full of BD MPEG2 howlers.

    It's also true that with a modern codec you don't need BD's capacity or bitrate.

    .....and finally I was also 100% true in giving the size of 'Black Hawk Down' which does not turn out (even with most of the 'extras' left in) to be close to the 50gb you imagined it was.


    Originally posted by Nextgen76: you don't own any Blu-ray movies so how would you know???? - Well, stickly speaking that's not entirely true.

    LMAO. :P

    Originally posted by Nextgen76:You don't, only what everyone say thats what all your Misleading info be based on. - I have friends with BD players, k?

    .....amd like I said I have a little collection of *cough* BD movies *cough*.

    Try not to take it all too much to heart tho, eh?

    ..........and may I just say how amusing I find it that you are not trying to claim here that this whole tread is a mountain being made out of a molehill.

    And I agree, its just some stuff that has to be refined in the process, besides its not like they dont refund the disks.

    I would love too see BD beat HD-DVD just because but thats not what this topic is it's the rot that worries me what if they really haven't made the disc that good this time around.

    What it's really only the first Generation and almost everyone just got into the regular DVD's and I am kind of made about this format I just got use too having dvds and burning them and all.

    I would like too know when they tv shows wil they put the whole season on 1 disk because they will be able too now or at least I think you could instead of making 7 disk for 1 season.

    17.6.2007 08:44 #23

  • Thoatih12

    Ok Blue-ray is not going to make it and HD-DVD will win this whole crap...its cheaper and cheaper for people to mass produce..also did I meantion its cheaper..


    back to topic we'll that sucks for Blue-ray disc!

    17.6.2007 16:57 #24

  • ZippyDSM

    BR dose have size about 10-20GB however its a wonky setup add Sony onto it and their anti consumer schemeing tis just not worth it unless they can prove they can dish out 100GB discs and there be nothing wrong with them and if it requires new hardware its almost pointless to try it.

    Still the brunt of the differences in BR and Hdvd is that sony has been heading the tech and effort a lousy 20GB is not goign to help sony win this they need to put the protections on the back burner get the bugs worked out and get 100GB made and done.

    Until then Hdvd offers a more coherent tech that slightly cheaper,2 discs will make up for anything needed, frankly 2 or 3 DVD9s are all thats really needed.

    the topic at hand is a non issue, all starting formats have issues hell this is like the 360 and its stock of poorly built 360s that have heating issues.

    it happens, hopefully this is not as bad as the 360s hardware issues.

    So now what, the war goes on until they give up or merge.

They'll have 7 discs, each with a bunch of features you'll never watch and charge a lot of money. That's how business works.

    they would adjust it around some anime is done about 1-2GB a 30 min ep for SD so HD would 4-10 a ep,at 4GB a ep you can put only 3 or 5 onto disc, however if they are smart they would offer a SD quality set at 800-1000GB a pop they could put most 25ep shows/seasons onto 1 disc and that would be worth 20 to me,100$ for a 25 ep show with fickle Americanizations just dose not cut it nor dose it cut it for TV shows.

    that looks like chemials misted on it. i lost timsplitters 2 to that once, and the disk looks the same! i sprayed lysol or febreeze, and it burned dots on my disk and my ps2, leaving an untuched disk print on the ps2 cover.

    I believe this is what will happen unless someone says screw the format war and waits for the next gen of dvds then I Believe HD-DVD is not enough capacity So BD disk will win and it will be around for what 5 or 6 years thats what we had dvds for maybe alittle longer 2013 thats the end of regular dvd 95-98% of people have dvd players by this time at least 40% will have BD dvd recorders and dvd players in there homes.

    By this time in 2010 HD-DVD will die a new format will be born it will be virtual DVD and this already excist if you look back it already was announced the next Gen DVD so I think I will wait because right now I have plenty of DVDs and I will have stuff too make on these things for a while.

    Plus once they have a dual burner for old and new dvds it will be the most spectacular thing ever.

    meh Hdvd can go to 150GB on new hardware and it seems to go over 50GB on BR will require new hardware as well, at least thats the vibe I am getting.

    its always something I guess, I was leaning to BR now I am leaning to Hdvd because they are simply "better".

    They can 'justify' a $60 $80 or even $99 price tag on tv series becuase of the perception that you are REALLY PAYING for 5 discs.. so at $40 on sale 5 discs aren't a 'bad' deal.

    Now look at the faces of the people who walk up and see ONE DISC selling for $64.98

    Yes there a whole season of tv shows on there (they know that) and yes they will have it all on one disc (they know that) and yes they really are not paying anything more than before when they got it on 5 discs (they know that) but I think you will find most people having trouble getting over the hurdle that they are paying $65 for ONE disc regardless of the content amount.

    It all comes back to the psychology of consumerism, packaging and pricing. Why do you think stores sell stuff for $xxx.99 or $xxx.48 instead of just saying screw it lets round it off... because the CHANGE allows someone who buys something for $99.99 to say well I got that for under 100 bucks (yeah like that extra penny was gonna kill the deal... BUT IN SOME INSTANCES IT DOES! lol Thats why the pricing scheme is set like that.)

    But anyways thats why you will not see whole seasons of episodes of 1 disc-- at least not until the format is ingrainded as the current SD dvd and priced the same as it is now... and even then you may just end up with multiple discs that have all those extras we all care about seeing.... like interviews with the hairstylist, or the interview with the 'best boy' talking about the time he ran an errand for director spielberg and brought back a live virginia pig thinking he was told to get a ham to buy instead of a ham on rye-- and thats why theres a pig seen running in the background at timecode xxx.xxx.xx because it was an inside joke for the cast and crew---blah blah blah

    Sony's DADC plant in the USA was well known for producing, especially towards the end of the LaserDisc era, discs known to suffer extensively from rot.

    Maybe they just are reverting to their old ways?

    BTW I hear theres more than 'The Presige' involved in this, 'Stranger Than Fiction', 'Pearl Harbor', 'Gone in 60 Seconds' and 'The Departed' have all been mentioned so far.

    One good reason I like this site is--in the course of others using wit and a small amount of indignation to discuss/debate the issues--I am sure the members who read the comments get a broader range of facts to figure out their own problems/needs/ideas. I like it. Human minds excel when provoked to prove a point. Well done, folks.

    Need to take with a drop of salt what most say or post :P

    do some digging and believe it or not for yourself ^^

    If this is real I don't see it hurting BR, BR has to much for/against it this is just random pressing of bad discs if its real at all,unless sony states otherwise..

    Although I only use regular DVDs and have no plans otherwise...my quest for KNOWING how things work is my fascination. For example, what would I gain with the newer technologies? Very little--a clearer picture--slightly. Another reason I want to know about technologies is to follow the Chinese domination in this field. They absolutely own the DVD market.
