A few years back, there were widespread predictions that similar things
were going to happen to audio and data compact discs on a wide scale.  So
far, those predictions don't seem to have been borne out -- I know that in
my own collection of music CDs, which numbers some 2,500 discs varying in
age from one week to 15 years, I've only seen two cases of bronzing or
delamination. Does anyone know where the "unofficial estimates" of DVD rot
in the 1 to 10 percent range come from?  And are there official (or at
least reliable) statistics on CD rot up to this point?
