I work for a small, non-profit organization that is looking to issue some of their publications on CD. The issue is whether to go for replication or duplication. The service they've been leaning towards only does duplication, but I've read that replicated CDs are much more reliable in that they are more likely to play in several different machines. I've tried searching on the web for further information contrasting replicated vs. duplicated, but came up with little useful info. I'd appreciate any feedback or education our HTF faithful could give me regarding the difference between the two, or recommendations on individual companies.
