"More than 100 years projected lifetime for DVD-R General" (Verbatim, http://www.verbatim.com.au/technotes/DVD-RGen\_Lifetime.pdf) Verbatim DVDs have a projected lifetime of more than 100 years so all these discs everyone is talking about must be the very cheap ones. It is because of Verbatim's patented Metal Azo Dye Technology; and this is why Verbatim discs are always double the price of everyone else. "In addition, Verbatim’s silver reflective layer is especially designed for best performance and longevity in combination with Metal Azo Dye, whilst our special UV-cured coating and polycarbonate adds to the durability. Due to these superior features an archival lifetime of more than 100 years is projected." (Verbatim, same as above) I know the Laser DVDs also have have Azo Dye and I remember reading somewhere that laser discs are very good too; thats the ones with the azo dye.
