Thanks for the additional facts. It is especially interesting that you report that using KHPro 4.103, making a .cdg file and burning it with Microstudio 2.613 made a disc with songs that play as expected.
We'll take a look at this today. We've not had this reported before to my knowledge, so I'm at a loss what to suggest.
I hope to have some facts to post today from our evaulation.
