Just a wild guess, but your changer script may need some 'sleep' commands
added to it.  On my drives, an 'mtx rewind' command will return long before
the drive is ready for another command, and an immediate attempt to read or 
write will fail, so I've added sleeps to some of the functions in it (actually
they may have already been in there, I may have just increased them, I don't
remember).
