Hi, David.  I was also seeing this "burncd: ioctl(CDRIOCFIXATE): 
Input/output error" whine from burncd with the NEC ND-3520A DVD R/RW 
drive I used to have in my workstation under FreeBSD 6.0 (and maybe 5.4 
before it).  However, the CDs I produced were still readable and 
bootable despite this message.

I'm not seeing this error message from my current workstation with an 
A-Open DUW1608 dual-layer DVD R/RW drive, nor had I seen this message 
while using the Sony CD-RW drive under FreeBSD 4.x-5.4.
