Medicloq! This was Sound Choice's anti computer plan at one point. It was short lived on discs 8700-8735 and a handful of others. They discontinued it as it wasn't able to play in some DVD karaoke player that were CDG compatable. When did you get the disc? New or used? They supposedly will replace it under their replacement policy for a non-mediacloq disc.
Some people have had luck getting them to work, most don't.
