I think this is the problem, in the case of having a changer.conf file, 
the tapedev specified here is the configuration number in the config 
file rather than the actual device itself.  You have it correctly 
specified in the changer.conf above, and thats all you need other than
the name of the changer.conf file in the amanda.conf file.
But I'd move the line " config 0" to the top of the list as I believe 
the config parsing starts with that statement and goes to the next 
occurance of "config 1" etc.

And again, this is spec'ed in the changer.conf file, so I don't think 
its needed here.
