Regarding the trick "Unmounting the unresponsive DVD drive" I would suggest the -f flag to umount, and maybe the use of tools like camcontrol or atacontrol. I know the article is about Linux, but maybe there are similar tools.
# umount -f /media/dvd
would force the unmount of the media. If this is not sufficient, tools like camcontrol or atacontrol could be used to reset or reinitialize the ATAPI components (the drive or the whole bus) in order to clear any persisting drive locks.
Just an idea... :-)
