I have a BDP-83 and I have noticed the same quirks as the above poster. Also one more (I don't know if this problem is with just my player or other people have had it too. I will contact oppo about it.) Sometimes (it had done this only 4 times since I have owned it) when the disk tray is ejected it will not pay attention to the command to pull tray back in. It will not pay attention to the "Play" command from either the remote or the buttons on the front of the unit. The only thing that fixes this is a gentle push in on the tray.
