Help with Virtualbox Enable Passthrough

[wah fun]

I have virtualbox 2.0.4 with an XP host and ubuntu 8.04 guest installation. Everything works great except brasero cannot see my cd drive, so I cannot burn a cd. I have installed linux guest additions and understand that the cd/dvd passthough option should allow the guest to see the CD/DVD drive. However, when I enabled passthrough in the VM setup, I cannot start the VM. I get an error: vbox status code -38(VERR_ACCESS_DENIED).

Thx
