Could you be a little more specific as to which specific methods
you're using to eject the DVD?

What does 'df' show after you've ejected the DVD?  What shows up on
the left panel in Nautilus' browser mode?

I'd speculate further, but it seems like the above answers will narrow
down the possibilities too much for a wide-scope shot in the dark to
be worthwhile.
