Once atapicam is installed, the CDROM device should have changed
from /dev/acd0c to /dev/cd0c. From my pc:
ls -alh /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above, /dev/acd0c should no longer represent the CDROM.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
