DVD-R's Not Working after few months

[dpbhyd]

Hi,

I have been making backups of my DVD's on DVD-R's for more than two years now. At first when i used to make this copy, I was able to rerun these DVD-R's on a DVD Player with out any problem. Now, After a few months these DVD-R's are not playable on the DVD player, but I can still play them on a computer.

I have been using DVD-Shrink to make backup of the DVD's.

Any Ideas as to whats going on.

Any help or suggestions are welcome.

Thanks

It could be that the discs are going bad. What brand / media code are they? Is it just older burned discs or also discs that you burn today?

If the DVD player is also having trouble with original pressed discs, the player could be failing or the lens could be dirty.

Even of your standalone player is not having trouble playing original, pressed DVDs, it still might benefit from running a DVD/CD cleaning disc on it. Maxell makes one that retails for approximately $10US...

Can you post details on the Lens cleaner. I think the disks i am using are from Ritek. and i also have DVD+R from verbatium

Can you post details on the Lens cleaner.The disc I use is "Maxell DVD,CD &CD-ROM Lens Cleaner" (It is a special CD with tiny brushes attached)

It may have to do with the write speed of the dvd-r's. I never had this problem with 2x or 4x blanks. With every batch of 8x's I got one or two flaky discs that did not read, or had pixellation errors, on a five year old Panasonic dvd player (RP-91). This player has no problems with glass-mastered dvds, nor with many titles that were backed up on 2X dvd-r's or 4X dvd+r's.

The vexing think is that a dvd-r which could not be read correctly on the RP-91 reads fine on a 2 year old cheapo Panasonic player.

I use TDK blanks, and have for many years. Now that I have started using 16X blanks, I predict my problems will increase, as far as my old dvd player is concerned. I don't know if this is comparable with 8x and 16x backups that do not work on playstation 2's, but clearly the manufacturers did not anticipate such heavy usage with dvd-r's nor with the thinner coatings that must be on the high speed blanks. Just my theory and two cents.

Did you put paper label on your backup disc, as this may cause the same problem.

I concluded after examining lot of discs that Ritek has problems (it may be Primedisc, Ridata etc..). They have some bad series, and all problematic discs are purchased in groups. I bourned 99% with 4x speed, so it can't be problem.

Labels: I observed strange thing, maybe is not strictly correlated with labels...
Lot of discs from one box were unreadable, actually drive didn't see them at all.
I noticed some thin soil film on surface, who knows how it appeared there? Maybe from label's glue, maybe it came from DVD's inner storage area, maybe from plastic case???
In any case washing it with warm water and hair shampoo solved problem. So, by inreadibility check surface, and wash by need.

A couple of years ago I was putting labels on my DVD's and very quickly (about the third or fourth they were played) they started pixelating and then became totally unplayable. Got and Epson R-200 and print directly to disk and the problem stopped and have not had a problem since.

My speculation on this:

Doesn't glue bond with a surface by 'seeping' into it? So maybe labels that are attached do not cause problems at first (assuming in cases where the weight of themself isn't), but when they have been left on for a while, the glue has worked it's way in to a layer and started to cause readability problems - I believe the reflective part of a DVD is behind the label side (correct?) and something making this not totally flat and shiny will cause read problems.

What's on the discs? recordings (dvd recorders) of TV broadcasts, or copied
dvd movies ? do not use minus (-R -RW) media, this will help in some cases, because of onboard copy protection CPRM in a lot of pc writers, (check with Nero Infotool)

Yes, I suspect that glue went through 2 acryl plate and recording layer, which is in middle of them. But it sounds little strange... Is it possible that some glue can go through acryl at all?
