For this player, I'm definitely in the 'if it aint broke, don't fix it' camp. I've read so many posts here of folks that upgraded the firmware and the result was a dead player. To add insult to injury, some were told by Samsung that the player not working was the user's fault, as they shouldn't have upgraded the firmware unless needed
I purchased the player when it came with the 1.25 firmware and upgraded only when I needed to, which was just one time, because of problems playing a single BD.
I'm now running 2.16 and it's been doing everything I need so far.
Best of luck.
