I've had some problems with using a DVD drive to install software in a WinXP Pro guest under Linux Mint 9. When the installer prompts me to swap CDs, the drive won't eject the disk when I press the eject button. If I eject manually (paper clip in eject hole) and insert the next disk, the system thinks it's the previous disk. Suggestions?

Solved: The DVD drive is IDE. I set it as Slave. I set the drive also as Primary Slave in the Storage section of the VirtualBox menu. It's now working - can swap disks and load/eject normally.

You needed to unmount the physical drive first. E.g. eject it from the Guest, then you can swap it. Another option would have been to detach the physical drive from the VM, swap disc and reattach it.
