Video's won't load

Hi,

I seem to have a problem loading the workout video's, whether it's a FB plus or not. The video just won't start and it seems as there are some pictograms missing on the bottom right. I've attached a photo to show, but sorry for the bad quality. I don't know how else to show it.

When I click on 'view on YouTube' I can perfectly watch the video, but I've got an FB plus account so I haven't got the adds, so...

Has anybody got the same problem?
