If you’re doing runs of 2000 you should definately go with Replication..or pressing as you call it. Usually anything over 1000 or so you should always go with replication if you can. DVD-R’s are a lot more compatable than they used to be so duplication is still a very good option if you’re doing a lower quantity of discs. You will still occasionally get a few discs here and there that people won’t be able to play but there isn’t much you can do about that. Most replication houses won’t even touch an order under 500, and if they do…you will pay a LOT more for it.
