This whole issue of CD-Rs and DVD-Rs being reliable for archiving precious files is driven by the multi-billion dollar wedding video-graphy business. This is an outright scam when the recording media wont even last the lifetime to show one's kids let alone the grand-kids. The other maxim is to keep the original recordings be they film or tape. And duplicate digital back-ups are really only an answer, but sadly not guaranteed for longevity. With hard-drives in order to keep the bearings and discs spinning it is necessary to play them on a regular basis.
