Both actually. Commercial disks are encrypted with the keys distributed to the players in their firmware AFAIK--this makes it so that only select manufacturers can play and/or create commercial video disks. For most uses there are better options than Blu-Ray disks; there is a small window in around the 100GB range that they might be useful but honestly it would be more reliable at similar cost to buy a used LTO tape system for that purpose. In general I wouldn't trust organic optical media; the lifetimes are much, much shorter than typically stated even when stored in a cool dry environment. Blu-Ray disks' primary use is for DRMed movie distribution; if it weren't for that they would have become obsolete long ago. :-) Tim -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iFYEARELAAYFAlTsBFQACgkQLaxZSoRZrGEvaADcCFtqSMfwEaO8vMK0TkCCT3qj cPnDu9QyYk2mzgDgzIoRVhiegLpY3jt945cJAwuABkBE+ZU5Goh88w== =tP9R -----END PGP SIGNATURE-----
