Your drive probably isn't MMC-capable.  Try updating the firmware.  For 
a Samsung go here: 
http://www.samsungoms-europe.com/samsung.php?section=download and get 
the firmware updating tool (it's called LiveUpdate or something).  It 
only works in Windows, so hope that isn't a problem.  If there's a 
firmware upgrade for your drive, it might fix this error and allow the 
FreeBSD dvd-tools to read your burner's configuration.
