I have firmware 1119F for the unit.
I received 2001 A Space Odyssey on BluRay for Christmas. This disc seems to do bad things to the player, lol. Before I could get it to play (I had sound with no picture) it took a bunch of stop/play/menu tries, eventually I got a non-main menu to pop up (the bonus features menu?) and could get the movie started (though not from the main menu, which I never saw)... after taking it out, I had to power-cycle the unit before it would play any other discs of any kind.
Is 1119F still the newest firmware? I can't even find that on LG's support site.
