Are you sure the ATAPI command used at that time is attempting to read
disc information and not, say, try to get drive capabilities?  I'm lead
to believe that the DVD drive he has doesn't support a particular ATAPI
function (long reads comes to mind).  ASC 0x24 ASCQ 0x00 is "Illegal
field in CDB" for most ATAPI operatons...
