Battlefront II DVD version



How can i make a working copy of battlefront II the dvd version, i made an image using alchohol 120%. The image does not allow me to play the game right off as in i get an error message:

Conflict with Disc Emulator Software detected. See for more details.

However when i enter the original disk the game loads fine, following the game loading the original disk can be removed and the game can then be played from the mounted image. How can i overcome this problem???

I have a similar problem with copying quake 4 dvd version as well.

Any help would be much appriciated thankyou>
