A Cautionary Note
If you pop a DVD into your Mac and the system doesn't recognize it and hitting Eject doesn't work:
Instead of following my lead and wasting a half-hour playing with Disk Utility and Googling for the terminal command to eject a disc (drutil tray eject, btw), make sure VMWare Fusion hasn't ganked control of the drive from the OS. If it has, just disable the CD/DVD drive on your VM. OS X will happily mount the disc and everything will be sunshine and rainbows.
Also, VMWare: treat the optical drive like you treat USB devices; if I don't have you focused when I put in a DVD, chances are I don't want you feeding it to my VM and sucking 28.5 minutes of my day away from me.
That is all.
