Are DVD's subject to chemical reaction?

Are DVD's used for storage susceptible to data loss like CD's are?

I didn't even know CDs are, I thought they worked on lazers and physical bumps (or dips) in the CD/DVD

As per dbarrow's post from mikehende's thread titled Backup Question http://kickenhardware.net/forum/showthread.php?p=7029#post7029

CD and cdrw ROT!
They never made a big public stink about it but it has been published time and time again.
Even the most expensive name brands have had the problem. It is a chemical reaction inside the strata of the cd. Amplified by heat and light.
Even cds stored in their cases in a temp controlled environment, in the dark, will eventually suffer.

If you have ever seen one (music I keep in the car are great for this) just hold it up to the light and look for little pinholes all over the place. You start losing tracks until it no longer plays.

If you value your cd collection, transfer them all to a HD ASAP!
You can always burn a copy from there.
