I have a disc open door on my Sony CX-860 ad 875P's, I usually use it to change new discs into the EZE slot to see what the movie is about, then if I like I assign a spot for it. I use a childs marbled composition book using different clors for different players, I don't depend on the GUI to remember should a lightning storm knocks off the power. The books are used with the 2 Pioneer F-1007 300 disc CD jukes also my favorites are movie music by Bernard Herrman and John Barry to name just 2. I have power doors on the Pioneer also with remote control or if I am in my wheelchair I can push the buttons I need to do right there and then. :)
