[Ham-Computers] DBD Terms, The Differences?

[Duane Fischer, W8DBF]

Hello All, 	
	
Can one of you explain to me what the exact difference between a "manufactured
DVD" and a "duplicated -R DVD" is? The duplicated is used for low quanity and
the manufactured, which uses a completely different format and equipment, for
higher quanities, such as more than a thousand. production	
	
I am wondering why the low quanity production is four times as much money to
have done and why two different formats are needed? 	
	
Thank you.
