Stefan, if you can't do it there try the Registry. Start>Run type:
regedit Navigate to
HKey_Local_Machine\System\Current Control Set\Enum\IDE\Cdrom drives.
rt click and select
Permissions. See what can be achieved there.
yes that i know that , but then i restrict the whole cdrom drive , i only
want to disable the option, to copy music with the media player option copy
music.
