I wonder if it is a copyright issue
often when video links to the UK and some to the US are posted I can't see them when everyone else seems to be able to
this is a link to a Canadian web site (TVO is a government of Ontario owned station with a format like PBS) and it could be that viewing is limited to those in TVO's viewing area (which I happen to be). I had no trouble viewing it a few minutes ago.
you will notice that George Richards who posted the link is also Canadian (but in Nova Scotia)
