Longevity of DVD discs?

Question

I created my home made movies from my videocam, and edited these to DVD discs using an editor program. The discs played fine and very clear with good sound. I used Shintaro blanks as well as TDK DVD-R's. I have had about 6 completed dvd movies made. It is three years down the track and I was playing it for my nieces coming from overseas. I was horrified that each one of them have started stuttering, there was shakes and then finally stopped midway through when I was playing it. I played on 2 different PCs and on my standard DVD player, but they have all the same problem. They're all different movies I made but all the disks have the same problem. They were stored on cd cases. Does anyone know why they have become like this? It couldn't be the software problem, because they worked perfectly when I created them. Does anyone have experience in dvd copies that have degraded over time.In commercial movies they shouldn't happen but mine seems to have deterorirated. I have to re-compile again

Answer 1

While I'm unsure of the degradation of DVD media, most especially recordable or re-writable, I've read that CD-ROM material (commercial) has a shelf-life of about 99 years.

However, I think a DVD player as well as the media degrades over time. I witnessed this firsthand when installing software from a DVD ROM drive I bought several years ago reading newer DVD media.

Also, you have to look at how the software portraying it deals with the media. It may or may not buffer information and provide it with a 'fluid' picture.

Answer 2

Degridation in DVD quality should not occur, as it is purely a digital signal read by a lazer.
Make sure the discs are clean and free of scratches.
Where do you store the discs? if they are stored near heat or direct sunlight this could affect them.
The plastic could warp and make them unplayable, that is why discs left in a car in extreem heat can go bad.
I do not know of any way to save the discs and restore them, sorry.
