I've been using my Sony 810 external burner for a year now, burning with it almost daily. Lately I've noticed that when you put the unit on its stand vertically, it has problems ejecting the tray. Thinking that it might be the door, I held it open and hit eject, you can see the tray move as if it wants to come out but its stuck on something. When you place the burner flat/horizontally, it has no problem at all. Anybody else run into this?? Its not a huge problem, but a trip to Sony might be needed although its out of the warranty period.
