help! SVCD can't play any more

    I started to burn SVCD back in 2000 for my home video. Since then I burnt
    around 20 SVCD on CD-R. All of them played very well on my Philips DVD
    player when they were freshly burnt. I recently play some of the oldest ones
    and found that they couldn't play on my DVD player (same one), or could play
    but with pause or blocky screen. The new ones (around 2 months ago) seem do
    not have problem. The problem seem to related to the age of the CD-R, the
    older it is the worse. The media I used are mixed brands but all cheap:
    Sony, Princo and others. But brand seems not related to the problem. The
    burning speed may be related, but unfortunately I did record their burning
    speed, so not sure about this. Did any of you have the same experience? Will
    using more expensive media (say Kodak, Verbatim, TDK) avoid this problem? I
    can rescue most of them by reading with my PC and I think (though haven't
    done yet) I can re-burn them to new media, but obviously I don't want to do
    this again every couple of years. What can I do?

    I am moving to DVD now (just burnt the first one 2 weeks ago). Shall I pay
    few times more for the expensive media?

    Some personal experience with DVD+RW, -R, & +R media that may
    (or may not) be helpful. If you write on the top surface of the
    CDs, then this might be pertinent.

    I started with DVD burning just about a year ago, using mostly
    +RW media.
    I had not done much CD burning prior, so I'm making no
    comparison.

    My cataloging technique is to write a 4 digit, indelible number
    on the disc, write the number and content on a cover card, and
    also record the same info in a data base. For the first 130
    discs, I had been writing the number on the top surface of the
    disc and I had paid no attention whatever to the marking pen's
    chemical content.

    In only a couple months I began to experience a few DVD player
    "glitches." Usually hesitation, sometimes "blocky" or pixilated
    frames. Like yourself, I was able to read and copy the discs in
    question on the PC; the new copies did NOT exhibit the problem.
    Although I don't have the tools to determine if the errors were
    caused by the ink, I *feel* that there were. I have since
    written the number ONLY in the hub and have not experienced any
    problems so far with discs catalogued this way.

    As DVD+R and -R are not re-usable, I had been writing the full
    title or description of the content on the media for things like
    videos, but using the content cover when more complex
    descriptions were required. I notice that the +R and -R media
    has a significantly thicker back surface separating the ink from
    the recording dye. So far, I've not had any similar experiences
    with these write-once media, but as a precaution I've changed my
    methods with them too.

    Since you mention using the cheaper CD media, I thought this
    experience might have a bearing, as that media might have been
    less thick and more prone to contamination from permanent
    marking inks.

    Unlikely. With recordable DVDs, the reflective and dye layers are
    sandwiched between two layers of polycarbonate. The marker won't seep
    through that.

    CDs are different, though. The reflective layer is right on top.
    Most recent CDs have some sort of protective layer on top, but it's
    still nothing near the design of the DVD.

    This is going to be a hard legend to kill, but no, old cds that show
    signs of failure these days seem unrelated to ink. Some seem
    label-related, but most are just the dye giving up. Many DVDs also
    failing in less than a year on the general market now.

    These failures also seem unrelated to disk brand. Or even within the
    same batch.

    Anyway, one of my DVD players has started playing all my SVCDs in
    black and white. Just cheap circuitry I guess.

    Will Dormann & ctrl-z,

    As I said, no proof. Like slipping on a condom (as opposed to
    slipping on a banana) it is just prevention of an ounce!

    Thanks for all the replies. I didn't write anything on the back of the disk.
    Instead, I use cd labels. Anyway, I believe the point is chemical, be it ink
    of markers or glue of labels, seems to be one of the possible causes.
    However, I recall some discussion about the durability of CD-R when it
    became popular couple of years back. People were talking about oxidation of
    the reflective layer. Some said it would happen in 10-15 years time. But it
    seems much shorter to me.

    I think the oldest cd burning experience is on audio cd copying. Any imput
    from this experience?

    Can you talk me more about "DVD also failing in less than a year"? Where can
    I read more about it? Which brand should we avoid?

    If you look at the packaging for the blank discs, you'll notice that
    they say to *not* apply any labels to them.

    There's a reason for this...

    Right now this is mostly anecdotal; just buzzing on the forums.
    Remember - these things have only been out in desktop PCs for a year.
    At first the rumblings are mentioning kiosk DVDs that play all day,
    but it may just be that those are the ones noticed first, and cause
    trouble (and posts) since they must be replaced.

    i.e., there could be many home movies on 12 month old DVDs that have
    already gone bad, but nobody will notice it until it's watched again.
    And then they may just think they did something wrong.

    Sorry, there's no big track record for any specific brand yet, nor any
    good way to tell if a manufacturer changes dye among the _same_ brand.
