    what i mean to say is could you imagine if a vcr refused to play some video tapes or record only you didnt know which ones till you bought them.dvd is an amazing media but if these problems keep coming up people will slowly loose interest.it wouldnt be to bad if it was 100 pound dvd players but when you read that arcam wont play certain discs it`s a joke

    Basically it only affects dual layer (rsdl) discs.If the disc has been poorly manufactured ,pulling the disc out of the case from the side, ( which some dvd cases instruct you to do ) can cause the two layers to seperate which makes your dvd player unable to read the lower layer. This results in badly corrupted visuals and sound (imagine skydigital in the worst thunderstorm ) and sometimes total freezing just after the layer change. I've had 2 discs go this way. I'm sure many people check their discs for this problem by watching the beginning of the dvd but you have to go to the layer change. If it happens to any of your discs you are at the mercy of the retailer who sold it to you, the studios just ignore you. One dvd e-tailer told me the studios don't admit to the problem and won't accept returns for this reason.

    Matt,

    I must admit I haven't noticed any problems thus far, but that is mostly as I have amaray cases for most of my films and almost never 'prise' from the outer rim of the disk.

    However, do you have a shortlist of the worst affected disks you have come across. I think it would make an interesting check for all of us.

    Regards,

    Matt

    I've blown my top a couple of times on this forum about rsdl(dvd) rot ( although I think nobody is that interested until it happens to them! ).Bit of interesting news, I bought a replacement copy of Aliens ( as mine had rotted ) and I was pleasantly surprised to see that Fox have changed the case making the dvd much easier to remove. This is the closest I have come to an admission that this problem exists from the studios (they completely ignore any correspondence on the subject )

    According to some (serious) scientific report I read rot can affect any CD/DVD, not only dual-layer disc.<br />This happens due to a chemical reaction between the different layers (i.e. the material of the different layers).<br />Experts have not agreed yet how long it will take to rot, but the numbers are somewhere in the range of 20-100 years while others quote "they will last a lifetime". But what's a "lifetime"!?

    "...what's a "lifetime"?

    ...20-100 years - that's what!

    my copies of aliens and the matrix took less than 2 years to rot!!!( not a bad lifetime for a fly)<br />To Matty N ,any dual layer discs are susceptible but particularly bad,it would seem, are alien trilogy, the matrix, l.a confidential and one other which escaped me at the mo. Type rsdl rot into a search engine (google) and you should find more info. I actually wrote to BBC watchdog about this but they weren't interested ( they sell dvds!!!)

    2 methods of bonding dual layer discs exist,

    The first and most common (as it's cheaper) involves using an adhesive, this type of disc can come apart at temperatures higher than 70 degrees C (impurities in a batch might reduce this).

    The second more expensive to produce as it's UV bonded and this does not separate at high tempeatures.

    So all of you with so called DVD Rot discs does your player get very hot (I know cheapo ones tend to) and is the disc very hot when it's been removed ?

    CW 2000 That's interesting,my player, a Panasonic a110, doesn't run hot but the 2 discs that have rotted were bought on a trip to Las Vegas where it did get pretty warm,none I've bought in this country or over the internet have rotted.

    Matt,

    thanks for the info. If my memory serves me correctly, Alien Trilogy and The Matrix were mastered around the same sort of time - hence factors such as increasing efficiency in production may have manifest these defects.

    Anyhow, I shall pursue this one for a bit. Anyone with any more info, please drop me a line with discs, origins and approximate dates of purchase.

    Thanks all, particularly Matt for raising my attention again!! I shall examine my collection carefully and transfer them to a temperature controlled environment. Freezer should do it. Felt like eating all that ice cream anyway.

    Regards,

    TJSMANGINA,

    I have had no experience of DVD rot myself and so cannot coment on the subject of this thread but what I would like to comment on is your rather distasteful 'sig', which you are shouting. Its not the kind of movie quote people generally use. Most of us use a funny or humourous line from a film, I hope your 'sig' isn't supposed to be funny! If so then I must call into question your mental state!! If I'm right its from a particularily gruesome scene (I'm sure people who saw the movie know which) from the excellent film 'American History X'

    I really don't think its appropriate <img src="confused.gif" border="0"> <img src="confused.gif" border="0">

    This thread is actually talking about two different problems - the two layer seperation problem is nothing to do with DVD rot, it's simply because the DVD is bent when removed from the case.<br />I have heard no case of the old laserdisc rot problem with DVDs myself, but have had a dual layer DVD die because of layer seperation.

    Ah trying to get in my good books by paying compliments to my site? Well it didn't work.....ok well maybe a little <img src="biggrin.gif" border="0"> Thanks for your kind words. As for your sig well...I have to say its not a line I would use and I'll take your word that your not a racist. I'm just so used to seeing racist comments on Counterstrike servers etc that I thought you may have been another obnoxious american teenager(with an interest in home cinema!)

    Its just that its a line from a racist character about to commit a brutal act ( which I know is only percieved in a racist context if you've seen the film) If the line was delivered by Christian Bale in American Pyscho commiting the act even on a black person the line would not be racist as the act would not have been racially motivated in that film. If that was the case then I don't think I would have a problem with the sig. Anyway it doesn't seem to have offended anyone else as no one else has commented so 'to each, his own'. I still wouldn't use that particular line myself though.
