problem accessing cd/dvd drive

[AN]

Hi VBox Team:

Many thanks for all your work to get VBox running on FreeBSD.  I am trying 
to use a program called Rosetta Stone on WinXP, but I am having trouble 
with the DVD drive.

I was able to install the application from the CD.  However, the way the 
program works I need to access a disk in the DVD drive that has data the 
program needs.

As per the wiki I tried to set the following, but it did not work:
the example config of /etc/devfs.conf:

perm cd0 0660
perm xpt0 0660
perm pass0 0660


When I insert the DVD, Windows reads the disk and opens a window called 
"Autoplay Application".  In the window there is a button that says Run 
Rosetta Stone.  When I click on the Run button, I get a error window 
"Cannot locate the DVD-ROM".  The message in the window says "Please 
insert the correct DVD-ROM, and restart application".  So, the problem is 
that I cannot read from the DVD drive inside a WinXP VM.  Any advice would 
be really appreciated.

Thanks in advance
