<<< MDK2 problem, please help >>>

I converted MDK2 CDItoNERO. I burned the image using all proper settings (Nero, of course) and then tried the game. It got to the loading screen where the dog gets chrome colored and spins. He Spins fine at first then intermittently, then continues to spin intermittently...no progress percentage showing. I also tried it with a dummy file and it didn't even get that far!!! What am I doing wrong???
