I have spoken with the ex-Marketing Manager for Nikkodo. He told me that Nikkodo modified the CDG timing on the discs they produced.

This was done to make them run only on the Nikkodo Karaoke Player box.
That explains why you are having problems duplicating their discs. We will work on modifying Microstudio to copy their discs, or play them either. They did a real no-no. They are no longer in business. Any wonder why?
