If I remember well, Virtua Cop 2 isn't selfboot. I guess you used Utopia boot CD before trying to run your game. If not, you have to run the boot CD and then swap with your game.
I burn with DiscJuggler 3.50.818 and I never had any problem. I find it much easier than Nero for DC games, but it's just a matter of taste. It should work with the images you try to burn.
There's a patch for Virtua Cop 2 to make it selfboot. Check here :
