Sony bdp s580 will not remember playback position

[dkimyfjywul]

This is my first blu ray player - all the sony dvd players ive owned remember playback position, even when you switch discs. This one will not; if i hit stop (yes, just once) and then eject - insert, it goes back to the main menu AND i have to sit through the fbi warnings each time.
What happened to sony players?

Oh Sorry! i may not have been clear: - yes it remembers playback position if you stop then start - but not if you take the disc out, put another in, then put the original back in - sonys use to do this
