When you say that you "copied to disk" do you mean that you burned a custom assembly with microstudio (or competitor)?

Does this disc play in Karaoke machines, or are the files simply copied onto a data disc?

If it is a data disc, are you careful to indicate that the changed file should go to the hard drive and not the disc drive?

If it is not a data disc, what are you trying to keychange? I've never tried to select something from an audio disc and I don't think you can. It sounds like that is what you are trying to do??

Are you saying that key changes downward have the problem and changes upward do not?

Also correct me if I'm wrong, I assume you don't mean kdg's but cdg's.
