Error: Unable to read AUDIO sectors...
 

This is what I'm getting:

Error: Unable to read AUDIO sectors 0 to 25 on device 1:0:0
Illegal command request (04h 00h 02h 05h 24h 00h)

I am trying to make up backup karaoke disc duplicates. Anyone have any idea what this means.

I am using a Pioneer DVD-RW DVR-104 4.00
It's supposedly new and came on my new Sony Vaio system (system is actually 1 yr old - may not be new by today's computer standards)
