True, I wouldn't guarantee a CD for more than 5 years and a DVD for more than 10.   On the other hand, with the turn around of laser tech, you'll more than likely be transferring older DVD archives to larger and larger formats before the disc is irreparably corrupted.  Most likely, my entire DVD archive (24 discs not including Poser Runtimes) will be converted to dual-layer within the next year or two - already have the drive to do it.

Archive media should be high-quality for sure.  And these and unique discs (for applications, for instance) should be stored in a dryish, cool environment protected from sunlight, dust, and other contaminants.  Mine are stored in a pocketed case and have not had any failures (cross fingers)  - some of these are already 7+ years since burning or purchase.
