I hope you don't mind me writing this, AS (and Mr Hedman) but this reply just seems so sketchy. "There were a couple of videos going around" is just so flimsy. Then you tell us that "Half the world would have seen it". Yet, if that is so, it wouldn't be so highly contested. Now it appears to have disappeared. Convenient, some might say.
Again, I hope you don't mind me pointing out, but given this basis, it seems that there are many out there (dare I say you included) who are quite happy to accept this rumour, on no evidence that we can see, because it suits your mind-set and a political agenda. So, in effect, you are prepared to accept this tale without any appreciable evidence, but are then quick to castigate the BBC on the veracity of their reporting.
One thing is for sure: the Trump camp will continue to flog this horse for their purposes. Indeed, Trump himself has repeated it since.
Perhaps Mr Hedman could provide us with the aforementioned video?
