iOS 4.3.1-Embedded video stop working iPhone 4

Hi,
I mistakely updated to version 4.3.1 and now embedded video have stopped working. For example-
www.odeon.co.uk
Trailers on this website worked in version 4.3, and now all you see is a rectangular box where the video is suppose to be.
I have tried restoring to factory setting but problem is still there, also tried clearing history, cache etc.
Can someone else check to see if they have the same issue, thanks.
