I don't think this identification of CD-Rs is foolproof in any direction. If you burn an audio CD you often get those 2 second gaps, but this really depends on the software and hardware used. Even worse edit #9534224 shows that there can be valid disc IDs of official releases that show the same characteristic. You can in some cases be pretty sure about whether a disc ID is home burnt or not, but not in any automated way. The 2 second gaps are an indication but not a proof. Cheers, Philipp -- Philipp Wolfer
