With the 870 and 875, if the player loses power fully (not just sleep mode offness) of if it "crashes" from a dirty disc, etc, it will scan the player and put the disc in the player in the first open slot. That can lead to all sorts of chaos with a full changer. Disc 176 winding up in slot 58 is a real drag, checking 1-57 before you find it in 58... My 870 does this alot and I am seriously looking at the 985, hoping that perhaps some of this funkiness is alleviated.
