Problem burning psx games.

I have been burning psx games for over a year. I even burnt protected psx games. The last few games I have tryed to burn will not burn, I keep getting errors. It down loads fine but it will keep getting errors(read write error or corrupted data)at different times when I go to burn them. Has this ever happened to you? I would like to know if they have other ways of protecting there games besides a chip reader. It could be my burner but it burns music fine. The games I have been trying to burm are
Duke Nukem(Land of the Babes),Parasite Eve and Creatures two. I went through 7 CD's I do not want to go through any more. Have a good one.
