Npl: copyprotection is not DRM.
Zeewolf: Yes it is. It is EXACTLY what DRM is.
Quote Wikipedia: DRM technologies attempt to control use of digital media by preventing access, copying or conversion to other formats by end users.
DRM is everything from codewheels to online servers. It's everything that prevents users from being able to copy their legally bought games/movies/whatever. DRM is everything from codewheels to StarForce to Steam.
Nope, even though I hate to quote
Wikipedia (Copy Protection): The term is also often related to and/or confused with the concept of digital rights management. Digital rights management is a more general term because it includes all sorts of management of works, including copy restrictions.
You simply cant do a 1:1 copy of console games (without expensive equipment), thats the reason they dont run - because you cant copy them and not because DRM is in place.
Alot of PC-games (without recent DRM ones) have similar measures, you can add alot stuff on a pressed CD/DVD-Rom you cant copy with a burner. So backups are no 1:1 copies and you need to fixup the game to work with them.
DRM can be used to enforce copy protection.. and typically is used for exactly that, but it goes beyond physical copy protection
