Doubt doesn't play. The menu selection doesn't show the animation in the background and after selecting play the screen just goes black and the disc spins indefinitely. This is with the newest firmware.
So I ejected the disc and put it into my PS3 (which I haven't updated in a long long time as it's in a room without Internet) and it played immediately.
I just can't understand how the PS3 is able to play a disc when the BH100 which I just updated cannot. To me this is absolutely the last straw with LG and this player. It's amazing to me how LG, a supposedly reputable multinational company, can abandon early adopters of what at the time was a premium product.
I paid the equivalent of US$1150 for the machine expecting that it would last for several years. I did not expect that I would be faced with constant issues of discs not playing which my PS3, costing half the price and not requiring multiple updates, could handle.
So I'm dumping the LG. Will give it away to a friend and use my PS3 to play Blu Ray discs until I find a more reliable player. One thing's for sure, it won't be an LG-branded product.
