As a follow up thread about my purchase of the Oppo 93 on Amazon on March 08, 2012
I received my unit yesterday from Amazon and it has this firmware:
I have no idea how old this firmware is but I am glad that I am able to play .mkv, .iso, and 3D .iso from my portable Seagate 1.5 GB via USB port.
I am a happy camper now.
I also have the HiMedia 900B and the Dune Smart H1 (that I bought about 1 year ago).
Anyway, I am glad that I bought the Dune before the price go up and I am also glad that I bought the Oppo 93 before the new firmware is installed by default. So buy your Oppo 93 from Amazon now folks before it is too late.
