First of all, I really don't think that the hard drive, or how it's mounted, is at issue. What about your cdrom icon on your desktop - does it have a little green triangle in the corner of the icon to indicate that it's mounted? Do you have more than one? Have you tried clicking the cd-rom icon? If a window opens when you do, it should be mounted, and you should be able to redirect Xine to the location shown in the address.

I don't know what's on your CD, but if it has an executable, you should be able to click and run from the window.
