Text doesn't show on JVC Karaoke Player - Superimpose switch was problem again

[kstaples]

I made my first cdg disk and was relatively pleased with how everything looked and worked. It played fine in microstudio and played fine on my "singing machine" player.
Then I took to disk to my local karaoke bar and was surprised to see a black, blank screen while the music played. What can I do to make sure the disks I record will play correctly in "all" karaoke players?

P.S. I am using the plextor drive you recommend, and am using memorex cd-r's.
