   E.g. "In addition you should be looking to add parity/recovery data to   
   your CD-R/DVD-R backup files, which serves two purposes: (a) allows   
   you to verify that the files are still readable and intact (b) allows   
   you to recover damaged files if you have enough recovery data. It   
   allows you to recover from scratches that the underlying ECC was   
   unable to correct for."   
      
   E.g. "I'd like to use QuickPar, or par2cmdline, to protect archives   
   stored on CD-R and DVD-R media."   
      
   E.g. "dvdisaster complements optical media [. . .] with error   
   correction data in a way that they are fully recoverable even after   
   some read errors have developed. This enables you to rescue the   
   complete data to a new medium."

   Impressive again! Are DVDs less durable?   
      
   Many of the white things which you show in this picture seem to be too   
   thin to be jewel cases. I read a suspicion in a different newsgroup   
   that sleeves might be OK for C.D.s but dangerous for D.V.D.s . . .

   #"My opinion is that the sleeves are not so good. Even without removing#   
   #them for a long time, they tend to jostle around and get scuffed up. I#   
   #have hundreds of CDs from the past five years and when I pull them out#   
   #of the sleeves I can see that they have gotten scuffed up some.       #   
   #Doesn't make a big difference for the CDs, but it might be a big deal #   
   #for the DVDs.                                                         #

   #Like the other person said, the holders for the DVDs can put a lot of #   
   #pressure on the disc. I have had some trouble getting DVDs out of some#   
   #of those locking mechanisms and had to bend the disc quite a bit while#   
   #prying it loose. I have seen at least ten different mechanisms, most  #   
   #of them seem to force me to be rough with the disc.                   #

   #Worse, if one of the prongs breaks off, the disc can slip off the     #
