Note that the DVD reads ones are different (real errors) than
the CDs ones... The CDs ones are buffer underrun (basically
the application or driver requesting more data than what the
drive actually transfer), we don't deal with that very well
at this point in the ide-pmac driver.
The DVD ones seem to be real errors, possibly wrong region setting
of the drive ?
