I'm getting "Sorry, that page doesn’t exist!" when I click that link.
Can you give us anything else to try, or more details, eg, what is the video and who/how were you referred to it?

I am using ver 47.0 of Mozilla Firefox, and Windows XP.
I am having issues watching certain video clips from a forum, and am getting the message ' This browser does not support video playback'.
I watch YouTube on a regular basis, so it must be something to do with settings?
The current problem seems to be from twitter. This is the file https://twitter.com/bbcarchive/status/761192472642854913 .
I do not use twitter, so is that the problem?
Thanks guys
Colin
