Interesting. I'm using a mid-2010 Macbook Pro. Why would this be a hardware issue when the video plays in Firefox, Chrome, and Safari? Is Opera doing something differently with hardware and h.264 playback?

Anyone else have ideas?

Thanks for the response. No luck with either setting, however. Still get the same error message.

Any other suggestions?

Here's a sample video that won't playback. https://twitter.com/OnlineMagazin/status/750648425306263553

Chrome and Safari handle these videos with no problems.

Thanks.
