Which Android tablet do you have?

Usually this error message in an indicator for a currently problematic (blocked) device capable of H.264 video playback. In our testing some devices caused crashes and we had to block playback until we fix the issues.

Thanks for your response. The tablet is a Visual Land vl-110. And it is running ics, not jellybean. I really like firefox since it is considerably faster than the built in browser, but the video problem could be a deal breaker
