Can't see the video, audio works
Arie, I've kind of sorted it. It seems that either refreshing the page a few times or rotating the ipad brings up the video. I suspect that it may be due to it being a fairly old iPad.
Hmm that's strange, could you try if you can see the video using another browser, for instance Chrome, Opera or Firefox?
Another thing you might want to try is deleting your cache, going here: https://www.google.com/search?q=deleting+cache+safari+ios
Let me know if this resolved the issue?
