I recentley purchased BDs of Batman: Under the Red Hood & Green Lantern: First Flight and am having identical problems with each. When playing the bonus features, the audio is out of sync with the video. If I stop and restart it will play correctly for a couple of minutes and then skip ahead again. These 2 discs are the only ones I've had the problem with. Again it's only on the bonus features.

I have a Samsung player and have downloaded the latest update so I don't think it's the player.

Anyone else experienced this problem?

Given that you have a Samsung BD player with the most-recent firmware, may be the issue as their latest update is glitchy with Warner Bros. (studio behind your Batman and GL discs) and Universal titles.

You can read more here.

Otherwise it may be a 'handshake' issue with your connection and you may need to detach and reattach the HDMI cable, depending on your set-up.

Guess I'm staying away from the latest update.
