It is worth pointing out that only replicated CDs can provide 100% compatibility
because they are all pressed from the same stamper whereas CD duplication burns the data onto existing blank media and hence every burn can be different all discs have errors on them and while they would not affect the actual data, they could affect the playability on some drives. There is no way to determine whether a CD that has been made via CD duplication will cause problems on a particular drive. If you need to be 100% certain that all CDs will play without any problem, you would need to go for replication rather than CD duplication.
