Try running the Disk Utility and repairing Permissions.
Trash the Limewire application and remove it's preferences.
Reboot and try again with the DVD.
Is this DVD a commercial one or one that you have burned yourself. Does this happen on ALL DVD's that you insert?
Interesting that it should attempt to launch Classic.
Let us know
I'm using OSX 10.3.9 and my DVD player will not open with the DVD being rejected. The computer attempts to open Classic but the DVD player refuses to open in that as well. Coincidently, around the same time Limewire refuses to open directly after saying 'Limewire Initialising" any ideas?
