Number 3 really bothers me.
3.Per the request from the studios, the ISO file playback function has been removed in this firmware version. The previous firmware had the ability to play ISO files, but it was an undocumented function and was never officially announced or supported. Future firmware version will no longer support ISO playback.
I've been converting all my dvd and Blu-rays to iso and was enjoying being able to play them all from my external hd connected to my OPPO BDP-93. Very frustrating and disappointed in OPPO. I guess I won't be upgrading the FW.
