The BDP-83 had an issue where the disc tray would become balky over time and at some point would just refuse to open. A workaround for it was to just leave a disc in the tray. Once OPPO had a permanent fix they had me ship the unit to them, they did the repair which was a new design disc tray and sent it back to me after they cleaned it internally, made sure the latest firmware was installed, and repackaged it to look like new. I even got a new set of white gloves and a carry bag. As far as I know only the BDP-83 was affected.
