I've tried with Sony 700mb cd's (with a bunch of "exelent optical", "perfect quality" lables) Dr.Hank 700mb cd's and some CD's with no label...but it's probably not a hardware problem, as I copy everything else perfectly. Warcraft III uses Sony SecureROM 2, but according to "www.gamecopyworld.com" nero shuld handle it (I have version 5..5.4.0, the latest I think)...
