Hi
We are truly sorry for the delays we have had. To understand what hit us between mid December 2000 and now, read this thread:

We are now almost back to normal, and responding to requests for the free upgrade serial numbers again.
Pertaining to this thread, as I posted earlier under bose's post, if you are having problems playing karaoke songs on a disc created with Microstudio,
change the write speed to 1x.
Sony Karaoke Players almost always require writing the CDR disc at 1x speed. Other Karaoke Players that also play DVD discs often also require writing the CDR at 1x. It is not a function of software, but the Player themselves.
