I get the following on dmesg: acd0: DVDR <PLEXTOR DVDR PX-716A/1.10> at ata1-master UDMA66 cd0 at ata1 bus 0 target 0 lun 0 cd0: <PLEXTOR DVDR PX-716A 1.10> Removable CD-ROM SCSI-0 device cd0: 66.000MB/s transfers cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed Perhaps you have to update your firmware on plextor drive? Plextor introduced advanced descriptions for new and/or corrected dvd types in there updates. Give http://www.plextor-europe.com/technicalservices/downloads/firmw_716A.asp?choice=DVD-Recorders a chance.
