These guys are great, bought the Oppo 93 player and found on several forums that the pro kit from bluraychip. Dk should be the best one for the job. Must say that their customer support is great, i downloaded the newest firmware from Oppo's site, just to find that the ISO playback was removed from this version, but when i contacted the guys at bluraychip they gave detailed instructions on how to downgrade the players firmware with the help of the pro kit. Perfect!
