On the question of DVD's "dying"...I noticed that DVD-R and RWs are constructed the same way as CD-Rs...clear acrylic w/ thin metal (usually aluminum) backing covered w/ paint or enamel. I would assume the same problems could happen. However...corporate DVDs (movie releases etc) seem to be a double sided format w/ strangely enough...side two identical to side one....sometimes the "making of" video will be there instead.
Close inspection of one of those seems to be...the thin metal sandwiched between 2 clear acrylic disks. Actually, molded this way...rather than assembled. that "sealing" of the metal from air would mean lack of oxidation or separation. So, these disks may have a very long life...
