I'm not sure if my problem is exactly the same, but it's pretty close. Written data DVD's aren't detected at all by my DVD writer.
1. Empty DVD's are recognized as such, and I can write to them with CD/DVD Creator. 2. Once written, if I re-enter the DVD it's not detected at all. It's not mounted. /var/log/messages: Dec 1 01:25:23 localhost kernel: [ 477.214504] cdrom: This disc doesn't have any tracks I recognize! python cdcaps.py /dev/hdb: CDO_USE_FFLAGS returned 13 got drive capabilities: 23fbef CDC_DVD_RAM support CDC_DVD_R support CDC_DVD support CDC_CD_RW support CDC_CD_R support got disc status: 101 System: Ubuntu Edgy AMD64 Pioneer DVD-RW DVR-110 However: 3.
