Go into a console as root and type:
ls -l /dev/cdrom
You will probably get something including bits like this:

-r-xr-x--- [something] root root [something] /dev/cdrom --> /dev/hdx

(x will be a number)
or maybe:

-r-xr-xr-x [something] root root [something] /dev/cdrom --> /dev/hdx

If it's the first one, then you need to type:
chmod a+rx /dev/cdrom
if you want anyone to be able to use it.

If it's the second one, then you'll need to do:
ls -l /dev/hdx
And you should get something like
-r-xr-x--- [some other bits] root root [something] /dev/hdx
Then you'll need:
chmod a+rx /dev/hdx

If you don't want all users to be able to use it, you'll have to do the following:

groupadd dvd
chown :dvd /dev/cdrom
chown :dvd /dev/hdx

Then you'll have to edit /etc/groups and add the user names you want to be able to play DVDs to the group dvd.
Hope this helps

because it just doesn't mak sense.... what normally happens when you eject a CD in the middle of playing a game in widnows? BSOD? it shouldn't be possibloe to do it...

as for why not when it's empty.... well.. there's isn't anything there! what do you expect to happen??

Linux is deisgned to be stable... how stable is it to be able to physically remove a filesystem while it's in use??
