Even though my Blu-ray player is brand new, purchased at Target two days ago, it still wouldn't play Avatar. If you are unable to play Avatar on your Blu-ray player, you will need to update the firmware of your player. Here is how you do it for a Samsung, which is what I have.

|USB Flash drive.|
The process is tedious, but the Samsung chat people stayed online with me while I did the update. After you do it once, be sure to go back right away do it again, like the instructions say. You know, "lather, rinse, repeat". But this time you should actually do it.
Keep in mind that your Blu-ray player is a hard drive, a sort of a mini-computer. And people like James Cameron can put things on Blu-ray discs without asking permission from Blu-ray player manufacturers like Samsung. That's what the problem is. This will probably continue for a few years so you will have to keep doing this. It's a hassle, but the Blu-ray picture is gorgeous!
