Actually cdrecord is not involved as it does not support dvd+rw. growisofs launches mkisofs and uses dd somehow to send the data to the drive. I have just discovered that you can do 'growisofs -Z /dev/sr0=/dev/fd/0' and pipe the mkisofs output into it though, so the same idea applies. I think I'll give that a shot as I don't think that buffer underruns are the source of my problem. Thanks, Mark -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
