The drive >must be older than I thought! No. Cdrecord has no knowledge of DVD+Plus, won't list it, and can't actually burn it. I suspect that some drives attempt to translate DVD-Dash commands to burn Plus media if that's what's in the drive, which would be why it seems to work in some cases. Growisofs does know about DVD+Plus. For Plus media one should use growisofs and not cdrecord. >It looks as though most drives offered now are double-layer.

Be careful what you pick up, though, as stores often have a mix of brand new and years-old drives. Look at the date on the drive. Plan on updating its bios when you get it home. ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
