I have seen a problem occasionally on my machine, though usually after
using it once. I have also ejected a DVD, inserted another, only to find
that FC6 still thinks the original disc is in the machine (volume label
is the same and I see the same old files in the nautilus window.

I have rebooted, and manually unmounted the disc to resolve this before
and have not seen it again for some time so I don't know if it will
recur (I don't often watch DVDs) but you could try a 'umount /dev/hdd'
or whatever your drive is.  You might give it a '-l' (lazy) also as I
find this helps a lot in the case of difficult umounts.
