all went well up to here

I didn't get an I/O error on the cmp, but I did get this:
cmp: EOF on file.iso

instead I tried my usual way of verifying cdrs:
$ md5sum file.iso
4f4a3c033db17cd090544932351eb970  file.iso
$ md5sum /dev/scd0
1862d022ca6cc665d45693663a8f545b  /dev/scd0

intersting...

isoinfo on both the /dev/scd0 and file.iso come out the same...
might have something to do with the UDF filesystem on the actual dvd.

This got no errors.

Just off hand, make sure you're using ide-scsi on that drive.  You
probably wouldn't have gotten that far without it though.  I guess this
means it's media or the drive...

here's my scsi_info to compare to yours
# scsi_info /dev/scd0
SCSI_ID="0,0,0"
MODEL="LITE-ON DVDRW LDW-451S"
FW_REV="GSB4"
