I'm noting that it DOESN'T say that 0 is loaded!

Which outputs nothing here, it just loads the tape.

If you are mechanically inclined, remove the changer from its normal 
location and re-attach the cables so that you can see what its doing.  
It might be something so simple as a rubber roller thats become 
polished up and is now slipping someplace in the robotics.   Or even 
a very bad case of dust bunnies.  Rubber belts will lose their 
tension and grip also, leaving the motor spinning its wheels and the 
device times out reporting the error chain above.  Home vcr's are 
infamous for that, to the point of the belts being designed out of 
them in recent times.
