Once atapicam is installed, the CDROM device should have changed 
from /dev/acd0c to /dev/cd0c.  From my pc:
	ls -alh /dev/cd0c
	crw-r-----  2 root  operator   15,   2 May 27 12:17 /dev/cd0c

Once you have atapicam working, burncd should not work.  Also, as per 
above, /dev/acd0c should no longer represent the CDROM.

I think the fact that the DVD-ROM is in the camcontrol devlist indicates 
that atapicam is working.  The question remains as to why 'cdrecord 
-scanbus' didn't work.

1. Are you sure the DVD-RW also burns CD's?
2. Do you know if anyone has gotten this Toshiba model to burn DVD-RW's 
using FreeBSD?

Good luck,
