Hello Following the problems I got with Moviestyles DVD+R, I've tried cdrecord-pro.
In dummy mode everything looks fine. But, dvd-record failed to write in readl mode: I ended with a mountable dvd with no data ?!?!?! Here's the output of the dummy mode. $ sudo cdrecord -v -dummy -dao ghibli-1.iso Cdrecord-ProDVD-Clone 2.01b31 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling Unlocked features: ProDVD Clone Limited features: This copy of cdrecord is licensed for: private/research/educational_non-commercial_use TOC Type: 1 = CD-ROM scsidev: 'ATAPI:0,0,0' devname: 'ATAPI' scsibus: 0 target: 0 lun: 0 Warning: Using ATA Packet interface.
