I have never tried to pipe into growisofs before so I cannot help with that but perhaps an alternative to consider. I use the program sdd to write directly to the drive. I have used this method a great deal under kernel 2.4 with a kernel patch. But I have only tested my own system at this point on 2.6.10 and no kernel patch. /bin/tar -cz some_files | /usr/local/bin/sdd of=/dev/raw/raw1 obs=32k Please note that it uses the raw device and sets the output buffer size to 32k. The raw device needs to bound the drive to be used like this: raw /dev/raw/raw1 /dev/dvd_drive_to_use Under 2.6 kernel with udev running I also have to do these commands first to create the raw device to bind. Then follow with the command above. You probably do not need these if not using udev. But you can check your system to see if they are present. mkdir /dev/raw mknod /dev/raw/raw1 c 162 1 raw /dev/raw/raw1 /dev/dvd_drive_to_use Good luck, James -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
