I have the BDP3280/12 blue ray player, which sometimes hangs shortly after starting a movie from the "Star Wars - The complete Saga" blue ray collection.
EAN: 4010232053084
It hangs in the movie (so after reaching the menu, selecting to play the movie).
I then have to pull the power cord, as the player does neither react to remote control, nor the keys on the device.
After this cold boot I can play the movie without a problem, so it does not hang at the same position again.
So far this happened on Episode 2 and Episode 4 disk.
There seems to be no newer firmware available.
