I have the same problem too. Before the update to Edgy works fine, but after it does not work. Nowadays i only can read/write cdroms and read dvd format, but can't read nor write data dvds.
This is the output of the revised script: $ ./cdcaps.py /dev/hdc CDO_USE_FFLAGS returned 13 got drive capabilities: 3bfbef CDC_DVD_RAM support CDC_DVD_R support CDC_DVD support CDC_CD_RW support CDC_CD_R support got disc status: 0 -- hal detects written DVD as empty https://launchpad.net/bugs/14692 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
