This works quite fine (except for CDs, which it probably isn't supposed to support). I can get the relevant information, like: % dvd+rw-mediainfo /dev/dvd | grep "Mounted Media:" Mounted Media: 11h, DVD-R Sequential or Mounted Media: 1Bh, DVD+R or Mounted Media: 1Ah, DVD+RW or Mounted Media: 10h, DVD-ROM Thanks, this will help a lot! Surprising finding: The message "1Bh, DVD+R" was obtained from a media labeled both "DVD+R" and "RW" by the distributor, even though the "paper DVD" on top of the spindle does not mention "RW". Maybe the distributor requires a friendly letter not to label DVDs with a property they do not have... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
