Strange Symbols on Web Pages

[leons]

What are these strange symbols I am getting on many web pages in Safari?

It's the play button in non-actionable form. Basically, the video is unplayable on the iphone. I've had that happen, and refreshed the screen and sometimes I am able to play the video then. Maybe someone with a little more expertise can provide more detail...

As above. Wait a few mins and see if they're playable.
