I've continued trying to burn an iso image using cdrecord and have discovered
that it fails when I use high speed media (4x-12x) but it works when I use 
standard media (1x-4x). Both media are Memorex and the drive is a 
Toshiba SD-R5002.  I even tried to limit the speed to 4x on the high speed 
media, but it still failed.  The record completes without posting any errors,
but when I try to mount it, I get mount_cd9660: /dev/acd0c: Input/output error
and an error on the console acd0: READ_BIG - MEDIUM ERROR asc=0x15 ascq=0x00 
error=0x00
