OK, that would imply that I do need to mount the burned media and compare
the individual contents.

I get media errors trying to simply access the device.
# md5sum -b /dev/cdrom
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1760
printk: 12 messages suppressed.
Buffer I/O error on device hdc, logical block 220
<this then repeats for section 1768, block 221, 1776/222 and so on>
Any ideas ?
Jonathan
