I was able to watch LFoDH even before the firmware update. Didn't try it with the new FW.
Now on to why I am here (1. It is late, and 2. I need a place to jot this down before I call Samsung tomorrow).
I did have one issue arise today, which may or may not have been the new firmware.
I watched POTC:AWE using the PCM track, and there wasn't a problem. However, I stop the movie at the end, during the credits and eject the disc. (Stop and then Open). I insert Meet the Robinsons, and I get a "Disc can not be played" error and the disc ejects. I retry. Same result. I then reinsert POTC, and I get the error again.
It was fixed with a Power cycle.
I was then able to watch Meet the Robinsons. The PCM track got distorted when Lewis is dropped off in front of the orphanage. I stopped the movie, and switch the disc audio to Dolby Digital, and there were no audio problems.
I Stop and Eject MTR, and then insert Harry Potter 2 (BD) with no issue.
HP:COS is playing behind me right now with no issues, but I am getting tired.
More maybe tomorrow.
