Try updating the firmware. Thats one of the first thing I did with mine, I believe I have the same model as you (2 of them actually), im too lazy to double check but the number looks familar. Going off memory there are 2 types of firmware for it, one is for US I think and the other international. I got the international one off newegg and I live in the US. To check go to my computer, than properties of your drive, hardware, select your drive, and finally the dvd region. If you see a bunch of options chances are it's international, if not and it says United States, well its the US version.
At least thats how I think it works to find out. Or you can do what I did and DL the US one first and try it to see if it works, and if it doesn't say a few choice words at the computer and give up hope for awhile till you say oh well and try the international. I know thats how I did things
