I got "No Country For Old Men" on Blu Ray via Blockbuster Online the other day. Last nite, I watched it on the PS3 in my theater room no problem. When I first turned on the PS3, it asked me to update it to the newer firmware, but I didn't do it cause I was in a hurry to watch the movie.
So, I watch the movie and everything was fine.
Tonite, my wife wanted to see the movie, but she just wanted to watch it in the living room. (We have another PS3 in there) So I turn on the PS3 in the living room, and it also said to update to the new firmware (2.20), and I went ahead and did it. Then, once that was all over, I put in "No Country", but I got a "This video cannot be played (80029940)" error message. Tried it again, same thing. Tried it a third time. Same thing. Tried it a 4th time, same thing. Had to apologize to my wife, and she had to just watch some TV instead.
I did some google searches on the 80029940 error message, and most people seem to think it has to do with a problem on the Blu Ray disk, but the disk played absolutely fine on my other PS3, so I don't think it has anything to do with the disk. I examined the disk, and it appeared to be in flawless condition.
I wonder if this has something to do with the new 2.20 firmware? I wonder if I put the 2.20 firmware on my theater room PS3, if that one won't play this disk either? hmm..... Strange.
