A DVD is always safe to remove as long as you don't burn it right now.
DVDs are (in the most circumstances) read only... so nothing to lose if just eject it the "hard way".

Perhaps you need to close the movie-player window before it'll let you?


lsof | grep -i dvd | less

see if there is any app accessing the dvd drive

a bit strange behaviour. I am using ubuntu 12.04 on hp pavilion laptop with cinnamon, nemo, nautilus (but he behaviour is showed in other cases). I have external usb hdd (ntfs formatted) and a crypted partition (luks format) on internal hd. when I unmount external hdds it doesn't show any message like 'it is now safe to remove drive' and sometimes says 'failed to unmount'. when I unmount the crypted partition it says always 'failed to unmount'. however hdds and crypted partition are always unmounted. it seems that the system fails to check and close applications and processes related to hdds and partition. I have another normal xfs backup partition on internal hd, which doesn't show such problems in unmounting.
